    Mixer The CTR 38 GHz uses a third harmonic mixer. The mixer uses a third harmonic local oscillator (LO) signal to convert the IF input signals to the 38.75-38.95 GHz microwave frequency band. The same LO is used to downconvert the incoming microwave signals to the receive IF frequency band.

  • Page 19: Low Noise Amplifier

    Duplexer The CTR 38 GHz uses the duplexer to combine and separate the transmit and receive RF signals, allowing use of a common antenna for receiver and transmitter.
