**HMC6147ALC5ATR: A 6 GHz to 20 GHz GaAs pHEMT MMIC Low Noise Amplifier**

The **HMC6147ALC5ATR** represents a significant advancement in high-frequency amplification technology, designed to meet the demanding requirements of modern microwave systems. Operating across an exceptionally wide bandwidth from **6 GHz to 20 GHz**, this GaAs pseudomorphic High Electron Mobility Transistor (pHEMT) Monolithic Microwave Integrated Circuit (MMIC) is engineered to provide superior performance where low noise and high gain are paramount.

A key attribute of this amplifier is its **outstanding noise figure**, typically as low as **1.8 dB** across a large portion of its bandwidth. This exceptional performance is critical for receiver front-ends in applications such as electronic warfare (EW), radar systems, satellite communications, and test and measurement equipment, where signal integrity is vital. The ability to amplify very weak signals with minimal added noise ensures superior system sensitivity and overall performance.

Complementing its low noise characteristics is its **high linearity**, evidenced by an output third-order intercept point (OIP3) of up to **+26 dBm**. This allows the amplifier to handle strong interfering signals without significant distortion, making it highly effective in dense signal environments. Furthermore, it delivers a substantial **small-signal gain of 18 dB**, which remains remarkably flat over the entire frequency range, ensuring consistent and reliable amplification.

Housed in a compact, RoHS-compliant **4 mm x 4 mm LFCSP package**, the HMC6147ALC5ATR is designed for seamless integration into space-constrained designs. Its single positive supply voltage of **+3V** simplifies power management, while the integrated DC blocking capacitors on both RF input and output ports further reduce external component count and board space. The device is also internally matched to 50 Ohms, streamlining the design-in process for engineers.

**ICGOOODFIND**: The HMC6147ALC5ATR stands out as a premier solution for broadband low-noise amplification, offering an optimal blend of ultra-low noise, high gain, and excellent linearity from 6 to 20 GHz in a highly integrated, easy-to-use package.
