This article proposes a 27‐33 GHz compact medium power amplifier with pole‐tuning technique in 130 nm CMOS technology. The resonant frequencies of three stages are arranged appropriately by pole‐tuning technique to achieve wide bandwidth. π‐type network is employed for input matching and L ‐type network is used for output matching. The measured results show the proposed amplifier has a peak gain of 12.5 dB at 30.2 GHz and a bandwidth of 6 GHz. The amplifier delivers an input 1‐dB gain compression point (IP 1dB ) of −4 dBm and a saturated output power ( P SAT ) of 11.7 dBm at 30 GHz. It consumes 42.72 mW with a core area of 412 × 215 μm 2 and the input and output return losses are better than −10 dB.
