**HMC1113LP5ETR: A 6 GHz to 5 GHz, GaAs pHEMT MMIC Low Noise Amplifier**

The relentless drive for higher data rates and greater connectivity in modern wireless systems, from 5G infrastructure to satellite communications, places immense importance on the performance of the RF front-end. At the heart of this critical subsystem, the low noise amplifier (LNA) serves as the first active component, setting the overall system's noise figure and signal integrity. The **HMC1113LP5ETR** from Analog Devices stands out as a premier solution, a **GaAs pHEMT MMIC** amplifier engineered to deliver exceptional performance across a wide **6 GHz to 5 GHz** frequency band.

This amplifier leverages the advantages of Gallium Arsenide (GaAs) pseudomorphic High Electron Mobility Transistor (pHEMT) technology. This material and structural choice is pivotal, enabling the device to achieve an outstandingly **low noise figure of just .8 dB** while providing a high **gain of 8 dB**. This combination ensures that weak desired signals are amplified significantly before much additional noise is introduced, which is crucial for maintaining sensitivity in receivers. Furthermore, the HMC1113LP5ETR exhibits excellent linearity, with an output third-order intercept point (OIP3) of 3 dBm, allowing it to handle strong interfering signals without generating excessive distortion.

Housed in a compact, RoHS-compliant 5-lead LP5 surface-mount package, this MMIC (Monolithic Microwave Integrated Circuit) is designed for ease of integration into high-volume manufacturing processes. Its unconditional stability and integrated matching networks—which require minimal external components—simplify board design and reduce both the bill of materials and overall footprint. The device is also protected against electrostatic discharge (ESD), enhancing its robustness in real-world applications.

Typical applications for the HMC1113LP5ETR are diverse and demanding, including:

* **5G NR base stations and infrastructure**

* **Microwave and VSAT radios**

* **Test and measurement equipment**

* **Satellite communication systems**

* **Point-to-point and point-to-multi-point radios**

**ICGOOODFIND**: The HMC1113LP5ETR is a high-performance, cost-effective MMIC LNA that excels in balancing ultra-low noise and high gain across a broad frequency spectrum. Its pHEMT technology and integrated design make it an ideal and reliable choice for advancing the capabilities of next-generation communication systems.
