Abstract :
This paper presents a newly developed single-chip RF transceiver MMIC for 1.9 GHz PHS wireless communications using a GaAs MESFET technology. The MMIC features a complete RF transceiver which includes an SPDT switch, a 2-stage LNA, a down-mixer, a double balanced up-mixer, an AGC amplifier and a 2-stage PA with an automatic gate-bias control circuit. The transceiver also features on-chip 50 /spl Omega/ impedance matching, with a chip size of 9.3 mm/sup 2/ and packaged in a 48 pin TQFP with heat sink.
