**High-Performance RF/Microwave Design with the HMC199AMS8ETR GaAs pHEMT MMIC Switch**

The **HMC199AMS8ETR** is a **GaAs pHEMT-based MMIC SPDT switch** designed for high-performance RF and microwave applications. Operating from **DC to 4 GHz**, this switch combines **low insertion loss** (typically 0.5 dB at 2 GHz) with **high isolation** (up to 40 dB at 2 GHz), making it ideal for demanding wireless systems, test equipment, and aerospace/defense platforms. Its **E-pHEMT technology** enables exceptional linearity and power handling, supporting **+38 dBm input IP3** and **+30 dBm power handling** at 1 dB compression.

The switch integrates **on-chip CMOS-compatible drivers**, allowing seamless interfacing with **FPGAs, microcontrollers, and DSPs** without external components. Its **compact MSOP-8 package** facilitates space-constrained designs while ensuring robust thermal performance. With **fast switching speeds** (10 ns typical) and **low DC power consumption** (<1 µA in standby), the HMC199AMS8ETR excels in **battery-powered and high-speed TDD systems**.

Designers leverage its **broadband performance** for 5G infrastructure, SATCOM, and radar systems, where signal integrity and reliability are critical. The device’s **ESD protection** (HBM Class 1C) and **operating temperature range** (-40°C to +85°C) further enhance its suitability for harsh environments.

**ICGOOODFIND**: The HMC199AMS8ETR exemplifies **advanced MMIC switch technology**, delivering **ultra-low loss, high isolation, and superior linearity** for next-generation RF systems.
