**HMC788LP2ETR: A Comprehensive Overview of the 5 GHz to 0 GHz GaAs pHEMT MMIC Low-Noise Amplifier**

The **HMC788LP2ETR** is a high-performance, gallium arsenide (GaAs) pseudomorphic High Electron Mobility Transistor (pHEMT) Monolithic Microwave Integrated Circuit (MMIC) low-noise amplifier (LNA) designed for a wide range of applications from **0 GHz to 5 GHz**. This frequency coverage, starting from DC, makes it an exceptionally versatile component in the RF signal chain, particularly where baseband or very low-frequency signals require amplification with minimal added noise.

Fabricated using a **advanced GaAs pHEMT process**, this amplifier delivers outstanding performance metrics. Its most notable feature is an ultra-low noise figure of just **0.5 dB** at 2 GHz, ensuring that the amplifier adds negligible noise to the desired signal, which is critical for maintaining sensitivity in receiver systems. Coupled with a high gain of **18 dB**, the HMC788LP2ETR can effectively boost weak signals while preserving a high signal-to-noise ratio.

The amplifier is also characterized by its excellent linearity, with an output third-order intercept point (OIP3) of **+28 dBm**. This high linearity performance allows it to handle strong interfering signals without generating significant intermodulation distortion, thereby preventing desensitization in demanding RF environments. The device operates from a single positive supply ranging from +3 V to +5 V, typically drawing 68 mA, making it suitable for both portable and fixed-installation equipment.

Housed in a compact, RoHS-compliant 2x2 mm **leadless chip carrier (LCC) package**, the LNA is designed for easy integration into space-constrained designs and is compatible with high-volume surface-mount technology (SMT) assembly lines.

**Typical applications** for the HMC788LP2ETR are diverse, including:

* **Infrastructure and Test Equipment:** Cellular base stations, microwave radios, and spectrum analyzers.

* **Military and Aerospace:** Radar, electronic warfare (EW), and communications systems.

* **Satellite Communication:** Very small aperture terminals (VSATs) and ground station equipment.

* **Wideband Cable Modernization Systems.**
