Abstract :
A novel monolithic integrated active mixer/LNA utilizing advanced pseudomorphic GaAs FETs has been developed for a mobile wireless receiver. RF coverage is 900 MHz to 2400 MHz. The mixer/LNA operates on a single 3 volt supply at 7 mA. The mixer provides 4 dB conversion gain with a -10 dBm LO drive. The LNA provides a 1.6 dB noise figure and 14 dB gain. The die is small and packaged in the SSOP-16 plastic package to keep costs low. This is the only GaAs PHEMT active mixer/LNA known to provide such performance from such a small DC requirement
