The Filter/Bridge PCB includes a modified 10 element Butterworth-Cauer low pass filter capable
of more than 60dB harmonic attenuation, a broadband RF power bridge, a modulation envelope
detector and associated level sampling circuitry. The entire PCB is enclosed in a metal
enclosure to form a module. The module is available in three different bands, Standard (190-
650kHz), Medium (500-1250kHz) and High (1500-1800kHz).
The Standard and Medium band filters are further subdivided as follows:
Standard Band: 190-300kHz, 300-450kHz and 450-650kHz
Medium Band: 500-750kHz, 700-950kHz and 900-1250kHz
These sub-bands are selected using on board jumpers, JP1 – JP10 as indicated in the tables
below.
