Active transmission mixer for a monostatic radar system

摘要

The invention relates to an active transmission mixer for a monostatic radar system with an oscillator input and an antenna port, two low-noise amplifiers connected in parallel, to which the superimposed oscillator and antenna received signal is applied on the input side, signal adaptation means being provided through which the superimposed oscillator and antenna signal applied to the respective amplifier input Antenna reception signal is individually adaptable for each amplifier, so that the amplifiers are operated alternately in the compression range in order to tap a mixed and amplified antenna signal at the transmission mixer output.
