Description

Trilithic 5VF Series tunable bandpass filters cover a frequency range from 3 to 4000 MHz with any single model covering an octave. Standard units are available with a five section response and have a 3 dB bandwidth of 5% ±1%* with low insertion loss values from 0.2 dB through 1.5 dB. VSWR is less than 1.5:1. Each unit is housed in a sturdy aluminum case with high “Q” cavities.
These cavities are iris coupled and shielded to minimize RF leakage. A constant filter response is maintained from the low end of the tuning cycle to the high end by varying the loaded capacitance of each section inversely as the frequency is increased.
The tuning arm is coupled directly to the driving mechanism which incorporates a precision vernier with a 6:1 ratio. An engraved dial which is calibrated directly in frequency indicates the center frequency of each filter response with resettability to within ±0.5%, thereby eliminating calibration charts or guesswork.
With the excellent filtering characteristic of the 5VF bandpass series, they are ideally suited wherever precision laboratory measurements are required. They are used for noise and harmonic reduction, diplexing and channel selection, and wherever a high level of attenuation is required below and above the signal band. Height is approximately 3 inches.
