The broad frequency expansion capability of series combiner technology ideally suits the often challenging requirements of multicoupling in analogue and digital military applications. The compatibility of series combiners with both analogue and digital protocols and the ability to cater to narrow and wide channel bandwidths within the one multicoupler provide the system designer with a unique solutions capability.

T-Pass® Tx Noise Suppression vs. Cavity Loss:
The curves shown below for Tx noise suppression represent the selectivity of typical quarterwave, 168mm (6.625 inch) T-Pass® cavity filters. Because T-Pass® cavities exhibit high loaded Q factors, excellent noise suppression and channel-to-channel isolation are achieved with 168mm (6.625 inch) cavities at a minimum separation of 250KHz. Additional cavities can be cascaded onto any channel in a T-Pass® system to customise an individual channel’s response if required.

Note: The use of cavity multicouplers for combining multiple channels with minimum frequency spacings may result in undesirable levels of isolator load heat dissipation due to interchannel coupling. Applications involving such requirements should be discussed with RFI prior to ordering to ensure the optimum solution is provided.
