The Model 3341-2400-144-EXT is intended for receiving Amateur satellites operating in the 2400 to 2450 MHz satellite band. It is designed using a two stage pHEMT MMIC LNA, with each stage followed by a SAW filter, which provides over 45 dB of image rejection. It has a local oscillator at 2256 MHz which is phase locked to an external 10 MHz reference. The 10 MHz incorporates a 10 MHz crystal filter to help improve phase noise and reduce spurious which might on the 10 MHz reference. Also employed is a high dynamic range double balanced mixer followed by an IF filter.
The IF of 144 to 154 MHz is well suited for use with the FUNcube Dongle as the wideband software defined IF radio.
