A Sandwiched-Slab-Transformer-Based SiGe Power Amplifier Operating at W- and D-Bands
IEEE Microwave and Wireless Components Letters(2020)
Abstract
In this letter, a 75.1–151.4-GHz silicon power amplifier (PA) is devised with the help of sandwiched slab transformer, which is proposed to increase the tuning ranges of coupling coefficient, quality factor, and conductivity. Being compact in size and simple in implementation enables it to be well-applied in multiple-way power combination. Based on this device, the fabricated PA in the 130-nm sili...
