Abstract :
A Ku-band fully-integrated 8-channel phased-array receiver with 2GHz wide IF-bandwidth on a 3.8*4mm die is presented. The receiver has extensive processing at IF-level, like polarization discrimination, but it consumes only 132mW per channel. Each channel has 40dB gain and a IP1dB of -66dBm. The wide bandwidth calls for constant group-delay implementations in the IF chain. A novel bipolar implementation for true time delay is proposed, with a continuous programmable delay range of 0...100ps. An active, linear-phase, poly-phase IF-filter at 1...3GHz is used. The high level of integration makes it possible to build an ultra-flat (1cm) array antenna with high resolution beam-forming.
