Samenvatting

A monolithic tunable bandpass filter for satellite receiver front-ends is presented. The nter frequency of the bandpass filter can be tuned from 0.4 GHz to 2.3 GHz. The filter is constructed using four transconductor-C poly-phase filter sections and has a 50 dB variable gain range. At 20 dB attenuation and at 30 dB gain the measured 1 dB compression point is -21 dBm and -56 dBm, respectively. Measured input IP3 is -12 dBm. The noise figure is 15 dB at maximum gain. An on-chip I/Q oscillator tracks the center frequency and enables automatic tuning. The bandpass filter dissipates 65 mW with 5 Volt supply voltage and occupies 0.16 mm2 chip area. The filter is realized in a standard 11 GHz ft bipolar technology.
