HMC1049

Overview

The HMC1049 is a GaAs pHEMT MMIC low noise amplifier operating from 0.3 GHz to 20 GHz. It provides 16 dB of small signal gain with a typical noise figure of 1.7 dB. The device delivers a P1dB compression point of 15 dBm and an OIP3 of 27 dBm. It requires a 7 V supply voltage and draws 70 mA of current. Input return loss is specified at 13 dB. The component is housed in a QFN-32 package and operates within a temperature range of -55°C to +85°C.

Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or discontinuation. Confirm that the specific package variant matches design requirements, as die-level options exist. Ensure compatibility with existing RF layout constraints due to the QFN-32 form factor. Check for updated datasheet revisions before finalizing procurement orders.

Selection Notes

Select this component when designing ultra-wideband LNA stages requiring minimal noise contribution up to 20 GHz. Consider the 16 dB gain profile for system link budget calculations. Evaluate thermal management needs given the 70 mA bias current. Verify impedance matching networks align with the 13 dB input return loss specification for optimal signal transfer.
