The circuit has been designed to produce a transceiver that switches the 4-element 1500 Ohm external BPF ends between the inputs and outputs of the two SA602s to reverse the signal flow for R/T ...
RFDN03C (DNC Mixer) is IR SSB Mixer used in transceiver application. The process used to design DNC Mixer is 0.1um GaAs pHEMT. This Mixer employs two ...
