Choosing the right filter type for RF applications depends on several key parameters and application requirements. Here’s a structured approach to selecting between LTCC, LC, Cavity, and Waveguide filters:

1. Frequency Range

LTCC (LowTemperature Cofired Ceramic):

Best for 500 MHz – 6 GHz (e.g., WiFi, 5G sub6 GHz, IoT).

Limited performance at higher frequencies due to parasitic effects.

LC (Lumped Element):

Suitable for DC – 3 GHz (lower frequencies).

Suffers from poor Qfactor at higher frequencies.

Cavity Filters:

Ideal for 1 GHz – 40 GHz (cellular base stations, radar, satellite).

High Qfactor, good for narrowband applications.

Waveguide Filters:

Best for 10 GHz – 100+ GHz (mmWave, radar, aerospace).

Excellent performance at extremely high frequencies.

 

2. Insertion Loss & QFactor

LTCC: Moderate Q (~100300), insertion loss ~13 dB.

LC: Low Q (~50200), higher insertion loss (~25 dB).

Cavity: High Q (~1,00010,000), low insertion loss (~0.11 dB).

Waveguide: Very high Q (~10,000+), ultralow loss (~0.050.5 dB).

 

3. Size & Integration

LTCC: Very compact, surfacemountable, good for integrated modules.

LC: Small but suffers from parasitic effects at high frequencies.

Cavity: Bulky, used in base stations and highpower systems.

Waveguide: Largest, used in aerospace.

 

4. Power Handling

LTCC & LC: Low to medium power (up to a few watts).

Cavity: High power (10s to 100s of watts).

Waveguide: Extremely high power (kW range).

 

5. Cost & Manufacturing

LTCC: Low to medium cost, massproducible.

LC: Cheapest but limited performance.

Cavity: Higher cost due to precision machining.

Waveguide: Most expensive, used in highend applications.

 

6. Application Examples：

Decision Flowchart：

1. Frequency > 10 GHz? → Waveguide (if power & budget allow).

2. Need ultralow loss & high power? → Cavity.

3. Small size & moderate performance? → LTCC.

4. Lowcost, lowfrequency? → LC.

 

Final Recommendation：

5G/WiFi (Sub6 GHz, compact): LTCC.

Cellular Base Stations (High power, low loss): Cavity.

mmWave/Radar (Extremely high frequency): Waveguide.

Consumer Electronics (Low cost, <3 GHz): LC.

 

 

Yun Micro, as the professional manufacturer of rf passive components, can offer the cavity filters up 40GHz,which include band pass filter, low pass filter, high pass filter, band stop filter.

On June 20, 2025, representatives of the Beijing Physical & Chemistry Testing Technology Society visited CIQTEK. A special seminar on “Innovation and Application of Magnetic Resonance Spectroscopy Technology” was held, along with on-site Nuclear Magnetic Resonance (NMR) data testing and comparison.

The Beijing Physical & Chemistry Testing Technology Society was established in 1980 as an academic organization voluntarily formed by experts in the analytical testing industry in the Beijing area. Its purpose is to unite and organize professionals in the analytical testing field within Beijing, promoting the development of analytical testing technologies. The society currently has over 1,000 members.

 

CIQTEK Launched NMR Spectrometer, Impressed Visiting Experts with On-site Performance

At the Beijing Spectroscopy Conference held from May 23 to 25, 2025, CIQTEK President Dr. Max He officially announced the new products — the 400 MHz and 600 MHz NMR spectrometers.

Although Dr. Max's presentation featured only a few slides on CIQTEK NMR instruments, it sparked considerable interest within the Beijing Physical & Chemistry Testing Technology Society. CIQTEK's emergence as a manufacturer of high-field NMR spectrometers was met with both surprise and excitement. The announcement quickly became a topic of lively discussion, with many experts expressing a strong desire to visit CIQTEK for an in-depth look at the instruments.

In response, CIQTEK extended a formal invitation to members of the Beijing Physical & Chemistry Testing Technology Society, including committee members and relevant experts, to visit the company for an on-site evaluation of their NMR research. This marked the Society’s first official delegation visit outside of Beijing.

On-site Benchmarking: Data Performance, Analysis Speed, and Quantity

During the one-day visit, participants engaged in in-depth discussions and hands-on data acquisition. The interaction was highly productive, with both sides delving into technical details and application insights. Numerous questions and suggestions were raised, making the session both interactive and constructive.

 

Reliable Spectral Data

The reliability of spectral data is the primary criterion for evaluating the performance of an NMR spectrometer. Therefore, sensitivity, testing efficiency, and spectral quality were key focuses during this on-site evaluation.

During the comparative testing session, two standard samples were prepared for live demonstrations:

• 0.1% Ethylbenzene — used to evaluate ¹H sensitivity
• 40% ASTM standard — used to evaluate ¹³C sensitivity

 

The detailed comparison results are as follows:

(1) ¹H sensitivity

The test results from other manufacturers are as follows:

• Brand A: Measured signal-to-noise ratio of 341:1 (sample not spinning)

 

• Brand B: Measured signal-to-noise ratio of 349:1 (sample not spinning)

 

• CIQTEK NMR Spectrometer CAN400: Measured signal-to-noise ratio of 458:1 (sample not spinning)

 

(2) ¹³C Sensitivity

The test results from other manufacturers are as follows:

• Brand A: Measured signal-to-noise ratio of 224:1 (sample not spinning)

 

• Brand B: Measured signal-to-noise ratio of 229:1 (sample rotations at 15 Hz)

 

• CIQTEK NMR Spectrometer CAN400: Measured signal-to-noise ratio of 224:1 (sample not spinning)

The on-site measured data confirm that the detection sensitivity of CIQTEK NMR spectrometers is on par with or exceeds that of the compared competitors.

 

(3) Testing Efficiency

Using the standard proton NMR test requirement (8 scans) as a benchmark, the time to complete a ¹H NMR spectrum on the CIQTEK CAN400 spectrometer was measured. While maintaining consistent spectral quality, the overall testing time was reduced by approximately 40%. This demonstrates the instrument’s high testing efficiency and reflects CIQTEK’s strong technical capabilities and accumulated expertise in various technical details. Improving efficiency while ensuring data reliability significantly enhances cost-effectiveness and is a key factor in gaining broad recognition.

In addition, non-standard samples were also tested on-site, and Dr. Junfeng Xiang, Vice Chairman of the Beijing Physical & Chemistry Testing Technology Society, was invited to operate the instrument firsthand. Before this visit, Dr. Xiang’s understanding of CIQTEK was limited to paramagnetic resonance solutions, but now it has expanded to include NMR solutions. He noted that CIQTEK’s NMR software incorporates original design concepts, which is commendable. Drawing on his extensive experience in NMR applications, Dr. Xiang also provided valuable suggestions regarding both software and hardware details.

 

Unprecedented Magnetic Resonance Speed

During this on-site visit, CIQTEK demonstrated an unprecedented pace of advancement in magnetic resonance technology. CIQTEK’s rapid development in paramagnetic resonance spectrometers has been well recognized. However, whether this rapid progress could be replicated in the field of NMR spectrometers was an open question before the visit. Now, we have the answer.

In just two to three years, CIQTEK has successfully developed world-class NMR spectrometers, marking a speed of technological advancement that is truly unprecedented.

What drives this remarkable pace is CIQTEK’s R&D team, which has leveraged its extensive expertise in developing EPR spectrometers and successfully translated it into NMR spectrometer innovation. More importantly, it showcases the strength and cohesion of an exceptional magnetic resonance research team.

According to CIQTEK’s introduction, their magnetic resonance research team consists of over 100 members, with 30 to 40% holding doctoral degrees in related fields. They conduct comprehensive research across multiple aspects, including technical principles, magnets, probes, spectrometers, and software.

 

Large-Scale Production and Delivery of Spectrometers

During this visit, we observed only two NMR spectrometers on display at CIQTEK’s Research and Application Center. Looking ahead, we hope to see tens, hundreds, or even more NMR spectrometers produced and deployed across various research institutes soon.

This growth will place higher demands on the manufacturer’s capabilities for large-scale production and technical support for application deployment.

 

This visit to CIQTEK was a great surprise, revealing a cutting-edge scientific instrument company with a professional team and a global vision.
