Bandpass Cavity Filters

 

Bandpass Cavity Filters
The Bandpass cavity passes one narrow band of frequencies and attenuates all others with increasing attenuation above and below the pass frequency. It is equivalent to a parallel-tuned circuit and is most often used for general transmitter spurious clean-up or a sharpening of a single receiver front end selectivity with or without amplification.

TX RX bandpass cavities (4", 6", 8” and 10") have adjustable selectivity characteristics (rotatable loops) to allow a trade-off between insertion loss (0.5--3.0 dB) and selectivity. Maximum power handling is typically determined by insertion loss setting.

T-Pass Cavity Filters are a variation of the Bandpass cavity used for our expandable multicoupler applications. Its general characteristics are nearly identical to a bandpass cavity but the output loop has a pair of N-connectors so it can easily be coupled to other channels.
