An 11 GHz-Bandwidth Variable Gain Ka-Band Power Amplifier for 5G Applications
(2019) 45th IEEE European Solid State Circuits Conference, ESSCIRC 2019 p.181-184- Abstract
A Ka-band,32-43 GHz,differential power amplifier (PA) for millimeter wave applications is presented. The PA is a three stage design with a nominal gain of 36 dB. A device periphery ratio of 1:2:4 is adopted for pre-driver,driver and final stage,respectively. To enable use of 2.7 V supply,a cascode topology was employed in all three stages. The input is 80 ω differential and the output load is 50 ω single ended. The PA has a variable gain of 36 ± 11 dB for use as variable gain amplifier. A saturation power of 17.8 dBm was measured at 35 GHz with a small signal gain of 34.5 dB,including output losses of 2-2.5 dB over band. The design is based on magnetically coupled parallel resonators to obtain the required bandwidth. A SiGe HBT BiCMOS... (More)

A saturation power of 17.8 dBm was measured at 35 GHz with a small signal gain of 34.5 dB,including output losses of 2-2.5 dB over band. The design is based on magnetically coupled parallel resonators to obtain the required bandwidth. A SiGe HBT BiCMOS process with fMAX = 330 GHz was used for fabrication. The PA is part of a front-end design,and its output thus faces an antenna interface with integrated LNA and TX/RX switches,and the input is connected to an on-chip variable gain amplifier.
