**HMC787ALC3BTR: A 6 GHz to 18 GHz, GaAs pHEMT Low-Noise Amplifier MMIC**
The **HMC787ALC3BTR** represents a significant advancement in **monolithic microwave integrated circuit (MMIC)** technology, designed to address the demanding requirements of modern wideband communication, electronic warfare (EW), radar, and test and measurement systems. Operating across an impressive frequency range of **6 GHz to 18 GHz**, this amplifier leverages **Gallium Arsenide (GaAs) pseudomorphic High Electron Mobility Transistor (pHEMT)** technology to deliver a combination of low noise and high gain that is critical for sensitive receiver front-ends.
A primary hallmark of this component is its **exceptionally low noise figure**, typically **1.8 dB** across the entire band. This performance is paramount in the first stage of a receiver chain, where it directly determines the system's ability to amplify weak signals without significantly degrading the signal-to-noise ratio (SNR). Complementing this low-noise performance is a high **small-signal gain of 19 dB**, which ensures that signals are elevated well above the noise floor of subsequent stages in the signal processing chain.
The amplifier is engineered for robust operation and integration. It features **unconditionally stable** performance across a wide range of operating conditions, mitigating the risk of oscillations and simplifying design-in. The inclusion of on-chip DC blocking capacitors at both the RF input and output ports further streamlines integration into larger systems. Furthermore, the HMC787ALC3BTR is housed in a **leadless, RoHS-compliant 16-terminal ceramic package** that offers excellent high-frequency performance and reliability. Its ability to operate from a single positive supply, typically consuming only **65 mA from a +3 V supply**, makes it suitable for portable and power-sensitive applications.
In practical terms, this MMIC is an ideal solution for amplifying signals in SATCOM, point-to-point radio, and aerospace and defense systems where wide instantaneous bandwidth and high fidelity are non-negotiable. Its combination of **broadband performance, low noise, and high linearity** (with an output IP3 of +23 dBm typical) provides system designers with a versatile and high-performance building block.
**ICGOOODFIND:** The HMC787ALC3BTR is a superior **GaAs pHEMT-based low-noise amplifier MMIC** that delivers **critical low-noise figure and high gain** across the entire 6 GHz to 18 GHz band. Its **unconditional stability, integrated features, and efficient package** make it an excellent choice for enhancing sensitivity and performance in a wide array of advanced RF and microwave systems.
