Abstract :
Presents experimental results for a second order switched capacitor bandpass filter designed to operate with a 250 MHz switching frequency and implemented using gallium arsenide (GaAs) technology. Measurements on a chip fabricated in a 0.5 mu m GaAs process confirm that the filter design, amplifier and switching components meet the desired performance specifications. The filter operates with high precision at 300 MHz and bandpass filtering at a switching frequency of 400 MHz is demonstrated.
