Band Pass Cavities 27-88 MHz
The TWPC-0410-1 is a 10" diameter, 1/4 wavelength, high-Q bandpass cavity filter with superior selectivity. These cavities reduce transmitter sideband noise, and protect
receivers against desensitization. The tuning range of these cavities is approximately +/-2.5 Mhz from center frequency as built. Calibrated adjustable coupling allows inser-
tion loss to be set from 0.5 dB to more than 2 dB, and a positive locking mechanism allows fast field tuning. Excellent frequency stability is ensured by a specially machined
compensator and Invar rod. The pass frequency is temperature stable from -30°C to +70°C. Cavity top plates are machined from 1/4-inch aluminum, and are heliarc weld-
ed to the cavity body. Rigid foam inserts support the tuner assembly for vertical or horizontal mounting. Similar metals and alodined aluminum help prevent galvanic corro-
sion. Silver plated tuners and beryllium copper finger stock provide non-corrosive low loss contact, and ensure reliable, long-term performance.
