**HMC6380LC4BTR: A 6 GHz to 5 GHz GaAs MMIC Medium Power Amplifier**

The **HMC6380LC4BTR** is a high-performance **GaAs MMIC (Gallium Arsenide Monolithic Microwave Integrated Circuit) medium power amplifier** designed to operate from **6 GHz down to 5 GHz**, a frequency range critical for modern C-band and satellite communication systems. This robust amplifier integrates a single-stage design that delivers exceptional gain and power output in a highly compact, surface-mount package.

A key feature of this amplifier is its **exceptional linearity and output power performance**. It typically provides a **saturated power output (PSAT) of +28 dBm** and a **gain of 16 dB**, making it an ideal solution for driving the final power amplifier stage in a transmitter chain or as a high-gain block in receiver applications. The device requires a single positive supply of +5V, drawing a typical current of 220 mA, which simplifies power supply design and contributes to overall system efficiency.

The HMC6380LC4BTR is fabricated using a **0.25 µm GaAs pHEMT process**, which is renowned for its high-frequency capabilities, excellent noise performance, and power efficiency. This technological foundation ensures the amplifier achieves a high **output third-order intercept point (OIP3) of +38 dBm**, a critical parameter for maintaining signal integrity and minimizing distortion in demanding multi-carrier and wideband applications. Furthermore, the device incorporates on-chip DC blocking capacitors at both the RF input and output, as well as a bypass capacitor for the supply voltage, ensuring stable operation and reducing the number of external components required.

Housed in a leadless, RoHS-compliant 4x4 mm SMT package, the amplifier is engineered for excellent thermal performance and is compatible with high-volume, automated PCB assembly processes. Its primary applications include point-to-point and point-to-multi-point radios, satellite communications, military and commercial radar systems, and a wide array of test and measurement equipment.

**ICGOOODFIND:** The HMC6380LC4BTR stands out as a highly reliable and efficient solution for mid-frequency C-band amplification. Its combination of **high output power, excellent linearity, and a compact form factor** makes it an indispensable component for designers seeking to enhance signal strength and quality in sophisticated RF systems.
