S-BAND-DOWN-CONVS-Band Down-Conversion Assembly

This product mainly consists of a dual-channel RF down-conversion module, a dual-channel IF front-end module, and a control & power supply module. It down- converts XX00MHz~XX00MHz RF signals to 70MHz IF signals, performs channel bandwidth selection and AGC, and outputs a level-stabilized IF signal. The required LO signal is generated internally. The product is mainly used in telemetry/remote control and mobile communications applications.
