An 8.4 GHz SiGe/Si HBT-Based MMIC Power Amplifier

A single-stage X-band MMIC power amplifier incorporating a SiGe/Si power HBT and lumped passive components is reported. The power HBT is characterized by an fmax of 67 GHz and a BVCBO of more than 24 V. The matching circuits were designed for maximum output power using on-chip spiral inductors and SiO MIM capacitors. Continuous wave measurements were made at 8.4 GHz, under class A operation. Th...

InGaP/GaAs HBT MMIC Amplifier with Active Balun for Ultra-Wideband Self-Complementary Antenna

Design of X Band High Power Amplifier MMIC Based on AlGaN/GaN HEMT

In this paper, we have presented an X band high power amplifier based on MMIC (Monolithic Microwave Integrated Circuit) technology for satellite remote sensing systems. We have used GaN HEMT process with 500 nm gate length technology with VD= 40 V and VG= -2 V in class E structure. The proposed two-stage power amplifier provides 25 dB power gain with maximum output power of 49.3 dBm at 10 GHz. ...

MGA-635P8 GaAs ePHEMT MMIC 3.5 GHz Low Noise Amplifier with Superior Noise and Linearity Performance

Depending on whether frequency domain duplexing or time domain duplexing (TDD) is used, one antenna can be shared by both transmitter and receiver via a frequencyselective diplexer or an RF switch. Additionally, a band-pass filter may be inserted before the LNA to prevent blocking or desensitization by a strong out-of-band interferer. However, both the duplexer and the filter have losses. As th...

A 1-8GHz Gallium Nitride Distributed Power Amplifier MMIC Utilizing a Trifilar Transformer

This paper describes the design and measured performance of a 1-8GHz power amplifier MMIC fabricated with a 0.15um Gallium Nitride (GaN) process technology. The process features a 100um thick Silicon Carbide (SiC) substrate and compact transistor layouts with individual source grounding vias (ISV). The design utilizes a non-uniform distributed power amplifier (NDPA) topology with a novel trifil...
