HMC1144-SX

Overview

The HMC1144-SX is a GaAs pHEMT MMIC medium power amplifier operating from 35 GHz to 70 GHz. It delivers 19 dB gain with a P1dB of 21 dBm and OIP3 of 28 dBm. The device requires a 4 V supply at 320 mA current draw. Packaged as a bare die in gel pack, it supports surface mount installation. Operating temperature ranges from -55°C to +85°C. This component serves as a wide-band RF solution for high-frequency applications.

Feature Summary

• Utilizes GaAs pHEMT technology for monolithic microwave integration
• Provides wide-band operation across the 35 GHz to 70 GHz spectrum
• Delivers medium power output suitable for VSAT input stages

Applications

• VSAT system input amplification
• Point-to-point radio links
• Satellite communication uplinks

Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or factory special order constraints. Confirm moisture sensitivity handling requirements due to the die package type. Ensure compatibility with existing thermal management solutions for the specified operating temperature range. Cross-reference ordering suffixes to confirm exact configuration matches design specifications before finalizing procurement orders.

Selection Notes

Select this component when a wide-band medium power amplifier is required for frequencies between 35 GHz and 70 GHz. Consider the bare die format for custom PCB integration rather than standard packages. Evaluate the 4 V supply requirement against available power rails. Verify that the 320 mA current consumption fits within the system's power budget and thermal design capabilities for continuous operation.

Part Context

The HMC1144 series represents Analog Devices' GaAs pHEMT MMIC portfolio designed for high-frequency wireless applications. The SX suffix typically denotes specific packaging or testing configurations within the product line. These devices are engineered for reliability in demanding RF environments, supporting both commercial and industrial temperature ranges while maintaining consistent performance metrics across the designated frequency bands.
