HMC263-SX

Overview

The HMC263-SX is a GaAs MMIC Low Noise Amplifier (LNA) designed for operation within the 24 GHz to 36 GHz frequency range. It operates on a single 3 V power supply with a typical current consumption of 58 mA. The device provides a gain of 21 dB and achieves a noise figure of 2 dB. Key performance metrics include a P1dB compression point of 6 dBm, an OIP3 of 16 dBm, and an input return loss of 12 dB. The maximum power dissipation is rated at 700 mW. It functions as a single-channel amplifier suitable for high-frequency RF applications.

Feature Summary

• Utilizes Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuit technology for high-frequency performance
• Provides low noise amplification in the 24-36 GHz band with high linearity characteristics
• Designed for surface-mount integration with minimal external component requirements

Applications

• Point-to-point microwave radio links
• Satellite communication systems
• Electronic warfare and signal intelligence receivers
• High-speed wireless data transmission backhaul

Procurement Notes

Verify the specific suffix designation when ordering, as the SX variant denotes a bare die configuration distinct from packaged versions like the LP4E. Confirm that the procurement channel supplies genuine Analog Devices Inc. components to ensure reliability. Check for moisture sensitivity handling requirements during storage and assembly. Validate that the application board design supports direct die attachment or appropriate substrate mounting techniques required for this form factor.

Selection Notes

Select the HMC263-SX when a compact, high-gain LNA solution is required for E-band frequencies. Consider the bare die format if space constraints preclude standard packages and if the manufacturing process supports flip-chip or wire-bonding directly onto substrates. Evaluate thermal management capabilities, as the device dissipates significant power. Compare against other MMICs if lower noise figures or different gain levels are prioritized over the specific 21 dB gain profile.

Part Context

This component belongs to the HMC263 series of low noise amplifiers manufactured by Analog Devices Inc. The series includes various packaging options such as the SMD/SMT QFN-24 package (HMC263LP4E) and the bare die version (HMC263-SX). All variants share the same core GaAs MMIC architecture and electrical specifications, differing primarily in physical form factor and mounting methodology.
