A high performance GaAs MMIC upconverter with an automatic gain control amplifier
A newly developed GaAs MMIC upconverter with an automatic gain control (AGC) amplifier is presented. The circuit is to be used in a 1.9 GHz RF transceiver for the Japanese PHS applications. The features of the upconverter are: (1) on-chip 50 /spl Omega/ impedance matching for all AC input and output signals; (2) a double balanced Gilbert cell and a 2-stage AGC amplifier with matching circuits that provide 23 dB conversion gain, -39 dBc LO suppression, -23 dBc image suppression and 30 dB gain control; (3) Adjacent Channel Power (ACP) of -70 dBc; and (4) a die size of only 2.87 mm/sup 2/ (2.52 mm/spl times/1.14 mm).
