**HMC7229LS6TR: A High-Performance GaAs pHEMT MMIC Low-Noise Amplifier from 17 to 31 GHz**

The **HMC7229LS6TR** represents a significant advancement in monolithic microwave integrated circuit (MMIC) technology, designed to address the demanding requirements of modern high-frequency systems. Operating across the **17 to 31 GHz** frequency band, this amplifier is a critical component for applications in satellite communications, 5G infrastructure, point-to-point radio, and military/defense systems.

Fabricated using a **high-reliability 0.15 µm GaAs pHEMT** process, the HMC7229LS6TR delivers exceptional performance where it matters most. Its primary strength lies in its outstanding **low-noise figure**, which is typically **1.8 dB** across the entire operating band. This characteristic is paramount for receiver front-ends, as it ensures minimal degradation of weak signals, thereby improving overall system sensitivity and range.

Complementing its low-noise performance is a substantial **gain of 18 dB**, which helps to boost signal strength and suppress the noise contribution from subsequent stages in the signal chain. The amplifier also exhibits excellent linearity, with an output IP3 (OIP3) of **+25 dBm**, making it robust against signal compression and intermodulation distortion in the presence of strong interfering signals. The integration of on-chip DC blocking capacitors at both the RF input and output, along with a matching network, simplifies board design and reduces the bill of materials, allowing for a more compact and cost-effective solution.

Housed in a compact, RoHS-compliant **6-lead LSCP package**, the HMC7229LS6TR is designed for easy integration into multi-chip modules (MCMs) and high-density PCBs. Its single positive supply voltage of **+3 V** at 65 mA current consumption further enhances its suitability for portable and power-sensitive applications.

**ICGOOODFIND:** The HMC7229LS6TR stands out as a superior solution for Ka-band and upper Ku-band systems, offering an optimal blend of ultra-low noise, high gain, and excellent linearity in a highly integrated, easy-to-use package.
