Overview
The HMC498 is a high dynamic range GaAs pHEMT MMIC Power Amplifier designed and manufactured by Analog Devices Inc. This amplifier operates within the frequency range of 17 to 24 GHz, making it suitable for various high-frequency applications. It provides 24 dB of gain, +27 dBm of saturated power, and 25% Power Added Efficiency (PAE) from a +5V supply voltage. The HMC498 is characterized by its small size, facilitating easy integration into Multi-Chip-Modules (MCMs).
