The design objectives, considerations, problems, and their solutions are described. The circuit is designed for a 1.9 GHz radio-frequency transceiver for the Japanese Personal Handyphone System applications. The features of the upconverter are: 1) onchip 50 Ω impedance matching for all AC input and output signals; 2) a doubly balanced Gilbert cell and a two-stage AGC amplifier with matching circuits that provide 23.0 dB conversion gain, -39 dBc LO suppression, -23 dBc image suppression, and 30 dB gain control; 3) an adjacent channel power of -70 dBc, and 4) a die size of only 2.87 mm2 (2.52 mm × 1.14 mm).||Source Title:||IEEE Journal of Solid-State Circuits||URI:||http://scholarbank.nus.edu.sg/handle/10635/115559||ISSN:||00189200||DOI:||10.1109/4.711327|
