K & L MIcrowave’s BT Series Tunable Bandpass Filters cover the frequency range of 125 to 4,000 MHz with each model covering a complete octave. These filters have 5 sections and a nominal 3 dB bandwidth from 1% to 10%. Standard models are available with a 5% 3 dB bandwidth offering low insertion loss values from 1 dB through 1.3 dB and a VSWR of less than 1.5:1. Each BT Series is constructed in a sturdy aluminum housing. Each section of the tunable filter is iris coupled yielding a low ripple Chebyshev response. Manual tuning of the BT Series is accomplished by a front panel vernier/dial assembly. Each dial is engraved with the direct-read-out center frequencies which eliminates the need for interpolating frequency calibration charts. |
