Lark-High-Speed-Header-03

Bandpass, Highpass, Lowpass Filters

low to high frequencies and everywhere in-between

Widely used in wireless transmitters and receivers, Lark offers a wide variety of bandpass, highpass and lowpass filters. For commercial and military applications demanding broadband and very small footprint surface mount technology, Lark’s ground-breaking LCP (Liquid Crystal Polymer), Extreme-Ultra Thin (XXUTMS) or Ultra-Thin (UTMS) series bandpass filters are ideal. For super high frequency applications, our 5G FH miniature bandpass filters fill the need. When a system requires direct current in the RF line, our Bias Tee (BT) series provides a solid design. Our new suspended substrate lowpass filters are lightweight and ruggedized for today’s military applications, and our SH Series of highpass filters feature small size and excellent temperature stability.
