A visit to Benchmark Lark Technology in Booth #11040 at IMS2022 will get you up to speed on the latest in high-performance RF/microwave filters and related components. With growing demand for all kinds of RF filter responses well into the mmWave range, the company will discuss how its diverse filter designs, including cavity, discrete LC, ceramic resonator, SIW, and PCB technologies, can serve applications from 10 MHz to 40 GHz and above.

Among the products Lark will show at IMS is its mmW-FH Series bandpass filters, built into SMT packages less than 0.04” high. Optimal for mmWave communications infrastructure applications, they can be designed to occupy 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 center frequencies from 5 to 30 GHz, 3 to 5 sections, and passbands from 2% to 5%.

Another example, Lark’s mmW-STL Series bandpass filters, are well suited for aerospace, SATCOM, defense, and mmWave communications infrastructure applications. Leveraging Liquid Crystal Polymer, PTFE, or rigid thermoset materials, these stripline filters fit five to 11 sections into SMT housings measuring just 0.25 × 0.25 × 0.033”. The miniature 50-Ω filters can be customized at center frequencies from 5 to 40 GHz and passbands from 10% to 25% to meet the most difficult SWaP-C challenges.

The latest news from Benchmark Lark Technology includes details on customizable ceramic monoblock bandpass filters for major telecommunications frequency bands from 400 MHz to 6 GHz. They feature lower passband loss and higher quality factor (Q) than traditional lumped-element LC bandpass filters but in a fraction of the size. Well suited for mass production and cost-sensitive applications, the monoblock bandpass filters can be built with power-handling capabilities to 10 W, making them a good fit for 5G small cells and repeaters.
