Summary: 
We have demonstrated the single-chip RF front-end GaAs MMIC for the Japanese Personal Handy-phone System. It has a high efficiency HPA, a T/R switch, a LNA and a low-distortion down converter mixer. The IC employs a negative voltage generator for use of single voltage DC power supply. The HPA provides an output power of 21.5 dBm, with an ACPR of 55 dBc and an efficiency of 35%. The LNA has a noise figure of 1.6 dB and a gain of 14 dB with current of 2.3 mA. The newly developed active cascode FET mixer has a high IIP3 of 1 dBm with a high conversion gain of 10 dB and low consumption current of 2.3 mA. The IC is characterized by high performance for RF front-end of PHS handheld terminals. The IC is available in a 7.0 mm6.4 mm1.1 mm plastic package.
