Abstract
The transmitter-receiver module includes a four-terminal coupler (2). An oscillator (1) and two diodes (4, 4') are connected to three of the terminals, while the fourth is connectable to an antenna (3). The diodes are used as a modulator during transmit, and as a mixer during receive. When transmitting, the oscillator is used as a signal source, and when receiving, it is used as a local oscillator. The module is implemented using fin-line technology. Several ways of realizing the oscillator are given.
