Abstract
Fully-integrated GaAs Q-enhanced second-order LC bandpass filters are presented. The filters are designed for a 60 MHz, -3 dB bandwidth centred at 1.88 GHz and 0 dB passband insertion loss. Passband gain (up to 15 dB) can be achieved with increased bias current before instability is encountered. These filters have potential application as image-reject filters in GaAs integrated transceiver designs.
