This Paper discusses a simple linear simulation technique to optimize the design of a traveling-wave amplifier (TWA) for best power and efficiency while avoiding extensive non- linear simulations. Thi...
While the general notion is that Silicon based CMOS is excellent for low-frequency digital application, and that GaAs based MESFET / PHEMT is dominating the high- frequency, high-power application, re...
We report the successful development of a broadband, high-linearity MMIC P A. This single P A is useful for multiple wireless systems including satellite mobile ground terminal, GPS transmitter, WiFi ...
We propose a new type of predistortion linearization technique: “Mirror Predistortion”. In a regular predistortion power amplifier (PA), the AM-AM and AM-PM distortion (Or I...
The HiFET (High-Impedance, High-Voltage FET) configuration is used to connect several semiconductor FETs both DC and RF in series, resulting in high DC bias voltage and high output impedance. The...
This paper reports the first MMIC using the High-Voltage/High Power concept with very broadband power performance. This GaAs MMIC power amplifier has a flat gain of 22dB and over 3W of saturated power...
We report a high-performance GaN amplifier operating from 100MHz to 3,000MHz. The best results included 100W output power, 22dB gain with 40% power- added-efficiency from 100MHz to 3,000MHz. This perf...
This article presents a design methodology for linearizing GaN HEMT amplifiers based on splitting a large FET into multiple parallel FETs with same total gate periph- ery and by biasing them individua...
A new device configuration is presented: The High-Voltage/High-Power device (HiVP). This original configuration can dramatically improve the power and decrease the complexity of designing power amplif...
mm-wave components are very expensive due to the high package and assembly cost. This paper describes a 0.25um PHEMT Ku-band 2- watt PA, and a 2.2dB NF LNA MMIC in a low-cost SMT package ($2.00). The ...
