A fully monolithic power amplifier(PA) for multi-mode front end IC integration is presented.The PA is fabricated in an IBM 7WL 0.18μm SiGe BiCMOS process with all the matching networks integrated on a chip. After load-pull test to find the best power stage size and layout optimization,the measured results show that the PA can obtain a 24 dBm maximum output power at 2.4 GHz,the output 1 dB compression point is 21 dBm at 5 dBm input,and the PAE is 18%.This PA is complete on-chip tested without any bonding wires and on-board matching, targeting fully power module integration in multi-mode system on chip.
