K & L MIcrowave’s BT Series Tunable Bandpass Filters cover the frequency range of 1.5 to 3,000 MHz
with each model typically covering a complete octave. These filters are available with 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 frequen-
cy calibration charts.
