HMC516

Overview

The HMC516 is a GaAs monolithic microwave integrated circuit (MMIC) low noise amplifier designed for operation in the 7 to 17 GHz frequency range. It provides a typical gain of 20.5 dB with a noise figure of 1.8 dB. The device operates from a single 3 V supply, drawing 65 mA of current. Key performance metrics include a P1dB compression point of 16 dBm and an OIP3 of 20 dBm. It features an input return loss of 10 dB and dissipates 1.25 W of power. The component is housed in a Gel Pack package and supports surface mount installation.

Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or factory special orders. Confirm that the specific package variant matches design requirements. Ensure compatibility with existing RF front-end designs regarding impedance matching and thermal management. Check for any recent obsolescence notices or lifecycle changes from Analog Devices before finalizing procurement plans.

Selection Notes

Select the HMC516 when a wideband LNA covering 7-17 GHz is required with minimal noise contribution. Consider its 3V supply constraint against system power budgets. Evaluate the 20.5 dB gain against cascaded stage requirements. Compare the 1.8 dB noise figure against alternative devices if ultra-low noise is critical below 7 GHz.

Part Context

The HMC516 belongs to the HMC516G series of low noise amplifiers manufactured by Analog Devices. It is part of a family of RF components optimized for wireless and satellite communications. The device represents a solution for integrating high-performance amplification into compact microwave circuits using established GaAs processing techniques.
