High frequency sending and receiving unit for radar system, has entrance for oscillator signal, distribution assembly to distribute oscillator signal on multiple signal trails

摘要

The high frequency sending and receiving unit (120) has an entrance for an oscillator signal, a distribution assembly to distribute oscillator signal on multiple Signal trails. Two or multiple mixer arrangements are provided which are connected with the distribution assembly for sending a send signal (TX) or for receiving of a received signal (RX). The mixer arrangement has a mixer and an amplifier for amplification of the oscillator signal and for the production of a send signal. An independent claim is also included for a mixer arrangement, which has an oscillator connection.
