Abstract

This work presents a broadband SiGe Power Amplifier (PA) for operation between 60-90 GHz covering both 71-76 GHz and 81-86 GHz E-Band sub-bands. It consists of a two-stage differential cascode amplifier using an LC-interstage matching network in the interface between the stages. Single-ended to differential conversion is accomplished by the use of two stacked 1-To-1 transformers, achieving a simulated insertion loss of 0.63 dB and 0.45 dB at input and output, respectively. The design has been implemented using Infineon B7HF200 0.18 pm SiGe HBT process with fp/fmax 200/250 GHz. Measured performance indicates that the PA delivers 12.6 dBm saturated output power (Psat) with 4.6% peak Power Added Efficiency (PAE) at 84 GHz while providing at least 6 dB of gain covering a frequency range from 62 to 90 GHz. The circuit consumes 102 mA from a 2.8 V power supply and occupies an area of 0.105 mm2.
