    This paper demonstrates the design of an E-band Doherty power amplifier (PA) based in an 130nm SiGe BiCMOS process. This design includes main and auxiliary amplifiers, lange coupler and a pre-amplifier. The designed power amplifier exhibits a saturated output power of 14.4 dBm and output referred P1dB of 11.7 dBm. The peak power added efficiency (PAE) of this amplifier is 19.2%. This PA shows PAE of 17% at P1dB and 11.6% at 6-dB output power back off. The peak power gain of this Doherty PA is 23 dB at 75 GHz with a 3-dB bandwidth from 60 to 80 GHz. The designed Doherty PA consumes DC power of 52 mW with a chip area of 900 μm × 800 μm without RF pads.
