HMC463LH250

Overview

The HMC463LH250 is a GaAs MMIC pHEMT Low Noise AGC Distributed Amplifier packaged in a hermetic surface mount package. It operates between 2 and 20 GHz, providing 13 dB gain, 3.0 dB noise figure, and 18 dBm output power at 1 dB gain compression. Powered by +5V with only 60 mA current consumption, it features optional gate bias (Vgg2) and adjustable AGC up to 8 dB typical. The device offers ±0.5 dB gain flatness from 2 to 14 GHz, with internally matched 50 Ω I/O ports and DC blocking.

Feature Summary

• Hermetic surface mount packaging for high reliability applications
• Integrated automatic gain control with adjustable range
• Internal 50 Ohm input and output matching with DC blocking
• Excellent gain flatness across the lower frequency band

Applications

• Electronic Warfare systems
• Electronic Countermeasures radar
• Test and measurement instrumentation
• Telecommunications infrastructure
• Microwave radio and VSAT links

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm lot traceability and MIL-PRF-38535 screening level (Grade B or S) if required by specification. Check for restricted availability status as supply may be limited or subject to factory special order conditions. Ensure environmental compliance documentation matches project requirements before finalizing procurement.

Selection Notes

Select this component when hermetic sealing and wideband low noise performance are critical. The integrated AGC simplifies dynamic range management in signal chains. Verify that the 2-20 GHz operational range aligns with system bandwidth needs. Consider the +5V supply requirement and 60 mA current draw for power budget calculations. Ensure thermal management strategies accommodate the specified power dissipation within the operating temperature range.

Part Context

This part belongs to the HMC463G series of GaAs PHEMT MMIC amplifiers designed for high-reliability RF applications. It complements other Analog Devices microwave components like the HMC462LP5ETR and HMC463LP5TR, offering similar functional capabilities but with distinct packaging options. The series targets demanding environments requiring stable gain and noise characteristics over broad frequency spans.

Replacement Considerations

Public confirmed substitute part numbers include HMC463LP5TR. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the alternative package type meets mechanical and thermal constraints of the existing design.
