2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014
This paper describes a fully-integrated 77-GHz distant-selective pseudo-random noise coded Doppler radar transceiver in a Silicon-Germanium technology. The transceiver is capable of measuring a vibration or a velocity of a target at a specified distance, which is programmable and can be configured very precisely in the transceiver, and suppressing all ...

2004 IEE Radio Frequency Integrated Circuits (RFIC) Systems. Digest of Papers, 2004
An active down-conversion mixer for automotive radar applications at 76 GHz to 81 GHz was realized in a 200 GHz f/sub T/ SiGe bipolar technology. A conversion gain of more than 24 dB and a single-sideband noise figure of less than 14 dB is achieved. The 1 dB output compression point is -4 dBm. The power consumption is 300 mW at -5 V supply voltage.
