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.
