**HMC602LP4E: A High-Performance GaAs pHEMT MMIC Low-Noise Amplifier for 24-40 GHz Applications**

The **HMC602LP4E** is a state-of-the-art **Monolithic Microwave Integrated Circuit (MMIC)** low-noise amplifier designed to address the demanding requirements of modern **millimeter-wave (mmWave)** systems. Fabricated using a high-reliability **0.15 µm Gallium Arsenide (GaAs) pseudomorphic High Electron Mobility Transistor (pHEMT)** process, this amplifier delivers exceptional performance across the **24 GHz to 40 GHz** frequency band, making it a critical component for aerospace, defense, and emerging 5G infrastructure.

A primary hallmark of the HMC602LP4E is its **excellent noise figure performance**. Achieving a remarkably low noise figure of **2.0 dB** across much of its operational bandwidth, it ensures that weak signals are amplified with minimal degradation. This high sensitivity is paramount for applications like radar receivers and satellite communication downlinks, where signal integrity is crucial. Complementing this is its **high linearity**, with an output third-order intercept point (OIP3) of approximately **+25 dBm**, allowing the amplifier to handle strong interfering signals without significant distortion.

The amplifier provides a substantial **small-signal gain of 22 dB**, which helps to elevate desired signals well above the noise floor of subsequent stages in the receiver chain. This high gain is coupled with consistent performance, ensuring stable operation across its wide frequency range. Furthermore, the device is engineered for **single positive supply voltage** operation (+3V), simplifying system power design and integration.

Housed in a compact, RoHS-compliant **4x4 mm LP4 leadless package**, the HMC602LP4E is designed for easy integration into multi-chip modules (MCMs) and high-frequency printed circuit boards (PCBs). Its architecture includes on-chip DC blocking capacitors and bias networks, reducing the need for numerous external components and streamlining the overall design process.

**ICGOOODFIND:** The HMC602LP4E stands out as a superior solution for high-frequency, low-noise applications. Its combination of an ultra-low noise figure, high gain, and robust linearity within a miniaturized package makes it an **indispensable component** for engineers developing next-generation communication, radar, and test equipment operating in the Ka-band and adjacent frequencies.
