Additionally, a buffer at the output is added for measurements. The amplifier was implemented in a 0.35 μm SiGe technology. For measurements the LNA was bonded to a substrate.

The two-stage push-pull amplifier uses monolithically integrated transformers for input and interstage matching and a monolithically integrated modified LC-balun as an output-matching network. For stabilization purposes and gain improvement in the operating frequency range a passive frequency selective feedback in parallel to the base-collector was introduced. The power amplifier is mounted on a 7 × 7 mm VQFN package. From a single 1.8 V voltage supply, the amplifier has a power-added efficiency of greater than 30\% from 11.2 to 13 GHz with a maximum of 37.3\% at 12.5 GHz.
