HMC462

Overview

The HMC462 is a GaAs MMIC PHEMT low noise distributed amplifier die operating between 2 and 20 GHz. It provides 15 dB of gain, a noise figure of 2.0 to 2.5 dB, and +15 dBm output power at 1 dB gain compression (P1dB). The device features an OIP3 of 26 dBm and input return loss of 19 dB. It operates on a 5 V supply with a current draw of 63 mA. The component supports a wide temperature range from -55°C to +85°C and dissipates 2.2 W of power.

Procurement Notes

Verify availability status carefully as the HMC462 may be subject to limited supply or factory special order conditions. Confirm that the required form factor matches the bare die specification rather than packaged variants. Ensure compatibility with existing RF layout designs before finalizing procurement decisions.

Selection Notes

Select this component when a bare die solution is required for custom PCB integration within the 2-20 GHz range. Consider the specific thermal management needs due to the die format and power dissipation characteristics. Evaluate if the distributed amplifier topology meets the system's linearity and noise requirements compared to packaged alternatives.
