HMC-ALH102

Overview

The HMC-ALH102 is a GaAs MMIC HEMT low noise distributed amplifier die operating between 2 and 20 GHz. It provides 11.6 dB of gain at 10 GHz, 2.5 dB noise figure, and +10 dBm output power at 1 dB gain compression while requiring only 55 mA from a +2V supply voltage. The device features a compact die size of 3.0 x 1.435 x 0.1 mm.

Feature Summary

• Utilizes GaAs HEMT technology for wideband low noise amplification
• Distributed amplifier architecture ensures consistent performance across the frequency range
• Designed for integration into MultiChip-Modules due to small form factor

Applications

• Wideband Communications Receivers
• Surveillance Systems
• Point-to-Point Radios
• Military & Space Applications

Procurement Notes

Verify the specific ordering suffix when purchasing, as it may indicate variations in packaging or testing criteria. Confirm that the component is supplied as a bare die suitable for custom substrate mounting. Ensure compatibility with your RF layout requirements regarding pad descriptions and thermal management before finalizing procurement orders.

Selection Notes

Select this component for applications requiring wideband operation from 2 to 20 GHz with low noise characteristics. Consider the +2V supply requirement and 55 mA current draw for power budgeting. Evaluate the need for MCM integration capabilities given the die format. Compare noise figure and gain specifications against system sensitivity requirements to ensure adequate signal integrity.

Part Context

This part belongs to the HMC-ALH series of wideband low noise amplifiers from Analog Devices (formerly Hittite Microwave). These devices are designed for high-performance RF systems where broad bandwidth and low noise are critical. The series includes various models optimized for different frequency ranges and gain profiles within the microwave spectrum.

Replacement Considerations

Potential substitutes include HMC772LC4, HMC-ALH435, and HMC-ALH482. Verify frequency range compatibility, as these alternatives cover different bands such as 2-12 GHz or 5-20 GHz. Check if the alternative part meets the required gain and noise figure specifications for your specific application.
