**HMC492LP3E: A High-Performance GaAs pHEMT MMIC Medium Power Amplifier from 5 to 20 GHz**

The **HMC492LP3E** represents a significant advancement in **monolithic microwave integrated circuit (MMIC)** technology, designed to address the demanding requirements of modern RF and microwave systems. Operating across an exceptionally broad bandwidth from **5 to 20 GHz**, this medium power amplifier is engineered for a wide array of applications, including point-to-point radios, satellite communications, electronic warfare (EW) systems, and test instrumentation.

Fabricated on a **high-performance GaAs (Gallium Arsenide) pseudomorphic High Electron Mobility Transistor (pHEMT)** process, the amplifier delivers a combination of high gain, excellent linearity, and superior power output. A key feature of this device is its **consistent 15 dB of small-signal gain** across the entire frequency band, ensuring robust signal amplification. It achieves a **saturated power output (Psat) of +25 dBm** and an **output third-order intercept point (OIP3) of +33 dBm**, making it an ideal choice for both linear and saturated power applications where dynamic range and signal fidelity are critical.

The HMC492LP3E is housed in a **leadless, RoHS-compliant 3x3 mm QFN package**, which is optimized for high-frequency performance and facilitates straightforward PCB layout and assembly. The architecture is designed for ease of use, requiring a single positive supply of **+5V and consuming only 120 mA**, eliminating the need for negative gate bias voltages. It is also internally matched to 50 Ohms, which simplifies design integration and reduces the need for external matching components.

**ICGOOODFIND**: The HMC492LP3E stands out as a highly versatile and reliable MMIC power amplifier, offering an exceptional blend of wide bandwidth, high gain, and impressive output power in a compact, easy-to-use form factor. It is a superior solution for designers seeking to enhance performance in next-generation microwave systems.
