HMC461LP3ETR

Overview

The HMC461LP3ETR is a high-linearity radio frequency power amplifier manufactured by Analog Devices Inc. utilizing GaAs PHEMT MMIC technology. Designed for surface-mount applications, it operates within the 1.7 GHz to 2.2 GHz frequency range. The device delivers an output power of 1 Watt (30 dBm) with a typical gain of 18 dB and a noise figure of 5.5 dB. It features a 16-lead VFQFN package with an exposed pad for thermal management. Key performance metrics include a P1dB compression point of 23 dBm and a third-order intercept point (OIP3) of 33 dBm. The amplifier requires a supply voltage of 5 V and draws approximately 1 A of current, dissipating up to 5 W of power.
