A compact power amplifier module (PAM) integrated with a power detector utilizing low temperature co-fired ceramic (LTCC) technology is presented for the IEEE 802.11a/b/g, GPRS and WCDMA applications. All MMICs' matching circuits were fabricated with the input and inter-stage matching circuits realized on-chip so that the PAM size is significantly reduced. The output matching circuit was implemented on an LTCC substrate to reduce power loss based on the advantages of high-Q ceramic components. The proposed PAM provides high power added efficiency and good linearity. Moreover, the measured results indicate the excellent performance of this PAM
