A1 Microwave are pleased to announce what we believe to be the worlds smallest low loss X band bandpass TX reject filters, our part numbers PB1496WB and PB1500WB.
These achieve 90 dB rejection over the whole 7.9 to 8.4 GHz band in a length of only 180 mm with insertion loss as low as 0.35 dB.
The lower cost PB1496WB is of brazed aluminium construction for strength, in fast it is strong enough to be stood on without affecting the performance so ideal for military applications that need to be "squadie proof".

For the absolute lowest loss the silver plated version the PB1500WB is the filter of choice, 0.35 dB loss at band edges..

These 2 products will tend to supersede our PB1109WN for applications needing a bandpass response but for absolute shortest length the PB1109WN is still the filter to choose. Please note this is not a bandpass structure.

These brazed aluminium TX reject filters complement our existing "squadie proof" RX reject filters for your transmitters :-
The PB1478WA has 60 dB RX rejection for only 0.3 dB insertion loss in 229 mm overall length. I huge length saving compared with traditional bandpass filters.
