HMC1049LP5E

Overview

The HMC1049LP5E is a GaAs pHEMT MMIC low noise amplifier operating from 0.3 GHz to 20 GHz. It provides 15 dB of small signal gain with a typical noise figure of 1.8 dB. The device features an output IP3 of 29 dBm and a P1dB of 14.5 dBm. It operates on a single 7 V supply drawing 70 mA. Internal matching to 50 Ω simplifies circuit design. Packaged in a compact 5 mm x 5 mm LFCSP-32, it supports temperatures from -55°C to +85°C.

Feature Summary

• Ultra-wideband operation spanning 0.3 GHz to 20 GHz for versatile frequency coverage.
• High linearity performance with significant output power capabilities relative to the noise floor.
• Integrated 50 Ω input and output matching eliminates external components for impedance alignment.

Applications

• Point-to-point microwave radio links
• VSAT and satellite communication systems
• Test and measurement instrumentation

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited distribution status. Confirm RoHS compliance details prior to integration. Ensure ESD protection protocols are followed during handling. Validate thermal management requirements for the LFCSP-32 package under continuous operation conditions.

Selection Notes

Select this component for wideband applications requiring low noise figures above 3 GHz. The 15 dB gain suits pre-amplification stages where minimal signal degradation is critical. Consider the 7 V supply requirement against available board voltages. The broad frequency range allows reuse across multiple product generations without redesigning the RF front-end.

Part Context

This part belongs to the HMC1049G series of high-performance GaAs MMICs. It is designed for general-purpose wideband low-power amplification. The LP5E suffix indicates the specific lead-free tape-and-reel packaging configuration compatible with standard surface-mount assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires verification of pinout compatibility and electrical parameter equivalence with existing system designs.
