Abstract :
A monolithic tunable bandpass filter for satellite receiver front-ends is demonstrated for the first time. The center frequency of the bandpass filter can be tuned from 0.4 GHz to 2.3 GHz. The filter is constructed using four gm-C 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 IP3 is -12 dBm. The noise figure is 15 dB. An on-chip I/Q oscillator tracks the center frequency and enables automatic tuning. The bandpass filter dissipates 65 mW with 5 V supply voltage and occupies 0.16 mm2 chip area
