Filter Can Hop Frequencies

Oct. 23, 2012

A line of frequency-agile filters operates with fast tuning speeds with models from 10 MHz to 1 GHz.

Frequency-agile filters from Lark Engineering are available with percent bandwidths of 5 to 20% from 10 MHz to 1 GHz with fast tuning speeds of 450 μs. These voltage controlled filters measure just 1.00 x 0.75 x 0.35 in. but can handle as much as 1 W input power. They consume only 1 mA at 0 to +15 VDC. The filters feature a 3/30-dB shape factor of 4.5:1. For more, click here.
