A 75 GHz monolithic-microwave integrated-circuit （MMIC） four- fingers cascode power amplifier in InP double heterojunction bipolar transistors （DHBT） technology with an fmax about 150 GHz was reported. The amplifier has 15 ×4 μm^2 total emitter area and exhibits a power gain of 12.3 dB at 75 GHz with 13.92 dBm output saturated pow- er. The amplifier achieves a peak output power of 14.53 dBm with 2 dBm input power at 72.5 GHz. The MMIC adopts coplanar waveguide （CPW） structure as the transmission line structure with area of 1.06 × 0.75 mm^2.
