Abstract
The invention relates to a transmit/receive switching unit for use between a transmit/receive converter and the transmission line of a transmit/receive device having a voltage source. The unit has transmitting and receiving channels with the receiving channel having a signal amplifier. An energy storage element such as a capacitor stores a part of the transmission energy on a continuing basis for operating the signal amplifier in the receiving channel. This scheme saves having to provide a separate line from a voltage source to the amplifier.
