Benchmark Lark Technology visualizes IMS mmWave filters in 2022

Company It will host Expo Booth # 11040 and focus on how its diverse filter designs can handle applications from 10 Mhz to 40 Ghz and above

Tempe, Arizona, June 14, 2022 / PRNewswire / – Benchmark Electronics, Inc. (NYSE: BHE), will provide visitors with the latest word on high-performance RF / microwave filters and components from Benchmark Lark Technology at the IEEE International Symposium on Microwaves (IMS2022) in 2022. For more than 30 years, Benchmark Lark Technology has been serving space and defense, telecommunications, industrial and space customers with custom RF / microwave filters and other high frequency components. With the growing demand for all types of RF filter reactions in the mmWave range, the company will discuss how its diverse filter designs, including cavities, discrete LC, ceramic resonator, SIW and PCB technologies, can handle applications from 10 MHz to 40 GHz and above. The IMS2022 exhibition is scheduled June 21-23, 2022in Denver Congress Center. The benchmark will be on expo stand 1011040.

Representatives of Benchmark Lark Technology will be available to discuss and advise visitors on effective custom filtering solutions, especially for meeting the requirements for reduced size, weight, power and cost (SWaP-C), which leads to the miniaturization of many applications . Representatives will share experience in the design and manufacture of 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 belt filters built into SMT packages less than 0.04 inches high. Optimal for mmWave communication infrastructure applications, they can be designed to take up very little PCB space and are compatible with microstrip and tape transmission lines, among other high-frequency PCB technologies. These filters can be designed and manufactured with custom center frequencies from 5 to 30 GHz, 3 to 5 sections and bandwidths from 2% to 5%. For example, a custom mmW-FH series filter for 5G 28-GHz band provides 610-MHz bandwidth centered at 27.95 GHz (2.2%) with less than a 5-dB loss of bandwidth insertion. omission. The 50 SI substrate integrated waveguide (SIW) filter has more than 35 dB rejection in the upper and lower stopping bands. It measures only 1.00 × 0.25 × 0.03 inches.

Lark series mmW-STL series filters are ideal for aerospace, SATCOM, defense and mmWave communications infrastructure applications. Using liquid crystal polymer, PTFE or solid thermosetting materials, these bandpass filters fit into 5 to 11 sections in SMT enclosures measuring only 0.25 × 0.25 × 0.033 inches. Miniature 50-Ω filters can be customized at 5 to 40 GHz center frequencies and 10% to 25% bandwidth to meet the toughest SWaP-C challenges. As an example, a 9-pole, 50-band 2.12-GHz bandpass filter centered on 8.7 GHz (24% bandwidth) provides more than 35-dB false off-band rejection from a small SMT packet.

The latest news from Benchmark Lark Technology includes details on custom ceramic monoblock bandpass filters for major telecommunications bands from 400 MHz to 6 GHz. They have a lower bandwidth loss and a higher quality factor (Q) compared to traditional LC band filters with grouped elements, but with a small part of the size. Highly suitable for mass production and cost-sensitive applications, monobloc bandpass filters can be built up to 10 W, making them suitable for 5G small cells and repeaters.
