Telewave-TWPC-8608-1-2-bandpass-cavity.pdf (98.00 KB) Item Details:
Factory-tuned with positive locking for easy field retuning. Adjustable coupling allows insertion loss from 0.5 dB to 2+ dB to fine-tune selectivity. The -2 model excels in crowded sites with minimal loss; multiple units can broaden the passband. Mounting rails included for multi-cavity configurations.
Temperature-stable (-30°C to +70°C) via machined compensator and Invar rod. Ground Loop design grounds coupling loops at DC for lightning protection and noise suppression. Rugged build: ¼-inch aluminum top plates heliarc-welded to body, handles up to 350 W (depending on loss). Alodined finish and matched metals prevent corrosion. Silver-plated tuners and beryllium copper contacts deliver low-loss, reliable long-term performance.
Telewave TWPC-8608 Bandpass Cavity Filters
Telewave TWPC-8608-1 and -2 are 8” diameter, ¼-wavelength high-Q bandpass cavity filters with outstanding selectivity. They pass a narrow band (800-970 MHz) while blocking others, reducing transmitter sideband noise and shielding receivers from desensitization.Factory-tuned with positive locking for easy field retuning. Adjustable coupling allows insertion loss from 0.5 dB to 2+ dB to fine-tune selectivity. The -2 model excels in crowded sites with minimal loss; multiple units can broaden the passband. Mounting rails included for multi-cavity configurations.
