1. A very small aperture terminal (VSAT) transceiver used in a VSAT terminal that communicates with a transponder of a satellite comprising:

  • a ceramic substrate board;

    a transmitter circuit and a receiver circuit operative at ka-band and including a local oscillator circuit and mixer for mixing local oscillator signals, formed on the ceramic substrate board, and each having microwave monolithic integrated circuit (MMIC) chips; and

    a microcontroller operatively connected to said MMIC chips and operative for controlling transceiver gain and output power based upon one or both of the received signal strength and the signal-to-noise information from an indoor unit of the VSAT terminal;

    a soft circuit board as a controller board and mounting the microcontroller, and including DC components;

    contact connectors connecting circuits on the ceramic substrate board and circuits on the soft circuit board as the controller board; and

    a housing enclosing the ceramic substrate board and soft circuit board.
