New Frequency Bands:
Series combiner multicoupler technology is ideally suited to new and emerging frequency bands. The design flexibility, broad bandwidth expandability, and overall implementation efficiency of series combiner ensures the maximum levels of future-proofing are available to site owners and network operators.

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.
