HMC1144

Overview

The HMC1144 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 at 100 mW output. Powered by 4 V at 320 mA, it features 22 dB input return loss and handles 1.77 W power dissipation. The bare die component functions within -55°C to +85°C.

Feature Summary

• Utilizes GaAs pHEMT technology for high-frequency performance
• Designed as a bare die MMIC for flexible integration
• Optimized for VSAT applications in the 40-70 GHz range

Applications

• VSAT systems
• Point-to-point microwave links
• High-frequency RF front-ends

Procurement Notes

Verify availability status carefully, as this part may be subject to limited supply or factory special orders. Confirm moisture sensitivity handling requirements due to its bare die nature. Ensure the specific ordering suffix matches your packaging needs, as variations exist between standard and specialized tape formats.

Selection Notes

Select this component for wideband medium-power amplification where size constraints favor bare die integration. Consider thermal management capabilities given the 1.77 W dissipation rating. Evaluate PCB layout complexity required for proper grounding and impedance matching at millimeter-wave frequencies.

Part Context

This device belongs to Analog Devices' portfolio of GaAs MMICs designed for wireless infrastructure. It serves as a critical building block for high-gain amplifier stages in satellite communication systems requiring operation across the E-band spectrum.
