A fully integrated 5.5×8.1 mm2 low temperature cofired ceramic (LTCC) power amplifier module for 5–6.5 GHz has been realised in a 40 GHz-fT -BiCMOS technology. No external components are required. At 1 to 2.4 V supply voltages output powers of 17.5 to 24.8 dBm are achieved at 5.9 GHz. The respective power added efficiency is 28 to 36%. The small-signal gain is 23 dB.
