**HMC260LC3BTR: A 6 to 14 GHz GaAs pHEMT MMIC Low-Noise Amplifier**

The **HMC260LC3BTR** is a high-performance **GaAs pHEMT MMIC Low-Noise Amplifier (LNA)** designed to operate across a broad frequency range from **6 to 14 GHz**. This device is engineered to meet the demanding requirements of modern microwave systems, where exceptional signal integrity and minimal added noise are paramount. Its core architecture leverages the advantages of Gallium Arsenide (GaAs) pseudomorphic High Electron Mobility Transistor (pHEMT) technology, which is renowned for delivering superior high-frequency performance, excellent gain, and outstanding noise figure characteristics.

A key performance metric for any LNA is its noise figure, and the HMC260LC3BTR excels in this regard. It boasts an impressively low **noise figure of just 1.8 dB**, ensuring that the amplification of weak signals introduces minimal additional noise, thereby preserving the integrity and quality of the received signal. This makes it an ideal front-end component for sensitive receivers in applications such as **electronic warfare (EW)**, radar systems, satellite communications, and test and measurement instrumentation.

Complementing its low-noise performance is its high **small-signal gain of 17 dB**. This substantial gain helps to elevate weak incoming signals well above the noise floor of subsequent stages in the receiver chain, such as mixers and intermediate frequency (IF) amplifiers. The amplifier also provides a high output IP3 (OIP3) of +26 dBm, underscoring its strong linearity and ability to handle higher power signals while minimizing intermodulation distortion, which is critical for maintaining signal clarity in dense spectral environments.

The MMIC is presented in a compact, surface-mount **6-lead 3x3 mm SMT ceramic package**, making it suitable for high-density PCB designs and integration into space-constrained systems. It requires a single positive supply voltage, typically between +3V to +5V, and incorporates an internal active bias network for stable and consistent performance over temperature variations. For applications demanding even greater resilience, the HMC260LC3BTR is also available in a hermetically sealed package variant (HMC260).

**ICGOO**

**ICGOODFIND Summary:** The HMC260LC3BTR stands out as a premier solution for **high-frequency, low-noise amplification**. Its exceptional combination of a sub-2 dB noise figure, high gain, and robust linearity across the 6-14 GHz band makes it an indispensable component for advanced military, aerospace, and communication systems where signal sensitivity and clarity are non-negotiable.
