چکیده

In this paper, a D-band power amplifier (PA) based on 0.5-μm InP DHBT is presented. Wilkinson combiners with broadband stepped-impedance matching are used, and the eight-way PA is designed for wideband power performance. As input power is fixed at 3 dBm, the PA exhibits a saturated output power of 16.8 dBm and 7.9% PAE at 150 GHz with >45-GHz 3-dB power bandwidth from 125 GHz to 170 GHz. Meanwhile the 1-dB gain compression output power is 15.9 dBm at 150 GHz. The >45-GHz 3-dB power bandwidth means a great flatness of power gain which is outstanding in reported D-band PAs to our best knowledge.

A high conversion-gain Q-band InP DHBT subharmonic mixer using LO frequency doubler

The paper presents analysis and design of a -band subharmonic mixer (SHM) with high conversion gain. The SHM consists of a local oscillator (LO) frequency doubler, RF pre-amplifier, and single-ended mixer. The SHM has been fabricated in a high-speed InP double heterojunction bipolar transistor (DHBT) technology using coplanar waveguide structures. To the best of our knowledge, this is the first...

A New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control

This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
