An Analog Linearizer Based on Amplitude Modulation with Even Harmonic Signals

This article proposes a novel amplifier linearization technique to achieve independent control of third- and fifth-order intermodulation products using amplitude modulation with even harmonic signals. A vector modulator modulates a fundamental signal with both second- and fourth-order harmonic components generated by harmonic generator circuits. It also generates predistortion third-...

Relationships Between Common Emitter, Common Base and Common Collector HBTs

Analytical expressions for the relationships between common emitter, common base and common collector HBTs are presented in this article. Further simplified expressions for noise parameters in the low frequency range are given. This technique is based ...
InP-based heterojunction bipolar transistors (HBT) have shown excellent microwave and noise performance and are very attractive for millimeter-wave and optoelectronic applications, such as low noise amplifiers (LNA), mixers, oscillators and other RF sub-system components. HBTs are almost exclusively operated in a common emitter configuration (CE) in amplifier design. However,...
