The 6CX9-1621.25-X10.5T11 from Reactel is a Cavity Bandpass Filter for the Iridium Satellite system. This airborne BPF has a passband from 1616 to 1626.5 MHz and a center frequency (Fc) of 1621.25 MHz. It has an insertion loss of less than 2.8 dB in the passband and provides attenuation of over 25 dB at 1614 and 1628 MHz. The filter is specifically designed with a narrow bandwidth and high rejection to isolate Iridium frequencies from outside interference due to Inmarsat systems and utilizes a special plating process. It is available in a module that measures 1.5 x 4.5 x 6.3 inches with TNC (F) connectors.
