Analog Devices Inc. HMC451 GaAs pHEMT MMIC Amplifier is a compact, medium power amplifier, offered in RoHS compliant bare die, SMT-16, and QFN-16 packages. Operating between 5GHz and 20GHz, the HMC451 amplifier provides up to 22dB of gain, up to +22dBm of saturated power and up to 24% PAE from a single +5.0V supply. Consistent gain and output power across the operating band make it possible to use a common driver/LO amplifier approach in multiple radio bands. This 50Ω matched amplifier does not require any external components and the RF I/O’s are DC blocked, making it an ideal linear gain block or LO driver for HMC SMT mixers.
The compact size of the Bare Die HMC451 makes it ideal for integration into Multi-Chip-Modules (MCMs). The HMC451LC3 QFN-16 and HMC451LP3 SMT-16 packages allow for the use of automated surface-mount pick-and-place manufacturing techniques.
