  ...possibly the worlds smallest low loss X band bandpass TX reject filters
 
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". PDF
 
For the absolute lowest loss the silver plated version the PB1500WB is the filter of choice, 0.35 dB loss at band edges.. PDF
 
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. PDF
 
 
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. PDF
 
The PB1466WA is the full 90 dB RX rejection version of the PB1478WA. It has only 0.4 dB insertion loss in 300 mm overall length. PDF
 
If you need the full 90 dB RX rejection but can't afford 300 mm of length then the PB1411WA folded version is the one to choose. PDF
 
All of these filters could be silver plated for even lower loss if required.
