摘要:
A radar system includes a transmit antenna for transmitting a first RF signal, a receive antenna for receiving a second RF signal, and a receiver circuit coupled to the receive antenna for processing the second RF signal and comprising a video amplifier having a temperature compensating attenuator. A radar receiver includes an RF amplifier, a down-converter and a video amplifier comprising a temperature compensating attenuator. The RF amplifier has an input terminal adapted to receive an RF signal and an output terminal at which an amplified RF signal is provided. The down-converter has an input terminal coupled to the output terminal of the RF amplifier and an output terminal at which a lower frequency signal is provided. The video amplifier has an input terminal coupled to the output terminal of the down-converter and an output terminal at which a filtered signal is provided.
