Benchmark Lark Technology forecasts mmWave Filters in 2022 IMS

Company It will host the Expo Booth Focus on how # 11040 and its diverse filter designs range from 10 Mhz to 40 Ghz and beyond.

TEMPE, Ariz., June 14, 2022 / PRNewswire / – Benchmark Electronics, Inc. (NYSE: BHE), Benchmark Lark Technology will give visitors a final look at high-performance RF / microwave filters and components at the 2022 IEEE International Microwave Symposium (IMS2022). For more than 30 years, Benchmark Lark Technology has provided aerospace and defense, telecommunications, industry and space customers with custom RF / microwave filters and other high-frequency components. Due to the growing demand for RF filter responses in the mmWave range, the company will discuss how its multi-filter designs, including cavity, discrete LC, ceramic resonator, SIW and PCB technologies, can be used in applications ranging from 10 MHz to 40 GHz. and above. The IMS2022 Exhibition is planned June 21-23, 2022in Denver Convention Center. Benchmark # 11040 will be on display.

Benchmark Lark Technology representatives will be available to discuss and advise visitors on effective filtering solutions, especially to meet the requirements for size, weight, power and cost reduction (SWaP-C) to promote the miniaturization of many applications. Representatives will share experience designing and producing waveguide, coaxial, and surface mount technology (SMT) filters, including mmWave frequencies, for applications such as 5G, automotive radar, and satellite communications (SATCOM).

Visitors can learn about Lark’s mmW-FH series bandpass filters, which are integrated into SMT packages less than 0.04 inches. Optimal for mmWave communication infrastructure applications, they can be designed to take up very little space on a PCB and are compatible with microstrip and stripline transmission lines, among other high-frequency PCB technologies. These filters can be designed and manufactured with custom frequencies from 5 to 30 GHz, with 3 to 5 sections and 2% to 5% bandwidth bands. For example, the mmW-FH series custom bandpass filter provides a 610-MHz bandwidth band for the 28G GHz band at 27.95 GHz (2.2%) with less than 5 dB of insertion loss. The 50 Ω substrate-integrated waveguide (SIW) filter has a rejection of more than 35 dB in the upper and lower stop bands. It measures just 1.00 × 0.25 × 0.03 inches.

Lark’s mmW-STL series band filters are ideal for aerospace, SATCOM, defense, and mmWave communications infrastructure applications. Using liquid crystal polymer, PTFE, or rigid thermoset materials, these stripline filters include 5 to 11 sections in SMT enclosures that are only 0.25 × 0.25 × 0.033 inches. Miniature 50 Ω filters at mid frequencies between 5 and 40 GHz and bandwidth bands can be customized from 10% to 25% to meet the most difficult SWaP-C challenges. As an example, a 9-pole, 50 Ω band filter 2.12 GHz bandwidth centered at 8.7 GHz (24% bandwidth) provides more than 35 dB out-of-band rejection SMT small packet from one.

Benchmark Lark Technology’s latest news includes details on customizable ceramic monoblock band filters for major telecommunication frequency bands from 400 MHz to 6 GHz. They have a lower bandwidth loss and a higher quality factor (Q) than traditional LC band filters, but only in part. Suitable for mass production and cost-sensitive applications, monobloc band filters can be built with 10 W power management capabilities to make them suitable for small 5G cells and repeaters.
