    Model AB808B493 is a cavity bandpass filter developed by Anatech Electronics for applications centered at 808 MHz. The 50-Ohm filter features a 33-MHz passband with less than 1.5 dB insertion loss and less than 0.2 dB passband amplitude ripple. Ideal for ...

    Model AB808B493 is a cavity bandpass filter developed by Anatech Electronics for applications centered at 808 MHz. The 50-Ohm filter features a 33-MHz passband with less than 1.5 dB insertion loss and less than 0.2 dB passband amplitude ripple. Ideal for filtering applications at cellular frequencies, the rugged filter handles 50 W input power using Type N connectors. Its out-of-band rejection is better than 30 dB from 764 to 776 MHz and from 851 to 870 MHz. The compact filter measures 193 x 50 x 45 mm and achieves better than 15 dB return loss in the passband. It is mounted to a system by means of threaded holes.
