Overview
The HMC451 is a general-purpose GaAs PHEMT MMIC Medium Power Amplifier developed by Analog Devices Inc. This amplifier operates within the frequency range of 5 to 20 GHz, making it versatile for various high-frequency applications. It provides 22 dB of gain and +22 dBm of saturated output power at 24% Power Added Efficiency (PAE) from a single +5V supply. The consistent gain and output power across its operating band enable the use of a common driver/LO amplifier approach in multiple radio bands.
