Overview
The HMC451-SX, produced by Analog Devices Inc., is a GaAs PHEMT MMIC (Monolithic Microwave Integrated Circuit) Medium Power Amplifier. This component operates within the frequency range of 5 GHz to 20 GHz, making it suitable for a variety of high-frequency applications. The amplifier is characterized by its high gain, saturated output power, and efficient power-added efficiency (PAE). It is designed for single supply operation at +5V and features DC blocked I/Os, which simplifies its integration into Multi-Chip-Modules (MCMs) and other complex RF systems.
