碩士 === 國立中山大學 === 電機工程學系研究所 === 89 === Abstract： This thesis was consisted of two parts. Part 1 introduced the procedure for designing the RF transceiver module in an IS-95 CDMA system using link budget analysis. Part 2 was focused on a CDMA power amplifier integrated circuit design for Personal Communication Service (PCS) applications. The design procedure was introduced in detail and implemented in MMIC for using GaAs HBT foundry provided by the GCS Ltd.. The designed linear gain, output 1dB compression point and power added efficiency (PAE) are above 30 dB, 27 dBm and 36.7% respectively under a single supply voltage of 3.4 V with the help of a diode linearizer. Harmonic components were suppressed more than 26 dB without use of any filters in the output. The adjacent channel power ratio (ACPR) and the VSWR of input port are below -45 dBc and 2 respectively.
