HMC1065LP4ETR

Overview

The HMC1065LP4ETR is a GaAs MMIC image reject low noise downconverter designed for the 27 GHz to 34 GHz frequency range. It integrates an I/Q demodulator, local oscillator (LO) buffer amplifier, and two double-balanced mixers within a single compact package. The device operates with a supply voltage of 3.3 V and consumes 180 mA of current. It features a leadless RoHS-compliant surface-mount QFN-24 package measuring 4 mm by 4 mm. The component provides high conversion gain and excellent sideband rejection, making it suitable for point-to-point microwave radio applications.

Feature Summary

• Integrates I/Q demodulation, LO buffer, and double-balanced mixers for image rejection
• Operates in the 27 GHz to 34 GHz K-band frequency spectrum
• Utilizes a compact 4x4 mm leadless RoHS-compliant SMT package

Applications

• Point-to-point microwave radio systems
• Satellite communications ground stations
• K-band radar systems

Procurement Notes

Verify that the specific suffix 'ETR' corresponds to the tape-and-reel packaging variant when sourcing components. Confirm compatibility with the 24-QFN footprint dimensions during PCB layout finalization. Ensure that the design supports the required 3.3 V power supply rail and thermal dissipation capabilities for continuous operation at maximum rated temperatures.

Selection Notes

Select this component when high sideband suppression is critical to reduce interference in up-conversion or down-conversion architectures. The integrated nature of the mixer and LO buffer simplifies the RF front-end design by reducing external component count. Consider the operating frequency range constraints and ensure the local oscillator signal levels meet the internal mixer drive requirements for optimal performance.

Part Context

This part belongs to Analog Devices' HMC series of monolithic microwave integrated circuits (MMICs). These devices are fabricated using gallium arsenide (GaAs) technology to achieve high performance at microwave frequencies. The HMC1065 specifically addresses the need for compact, high-linearity downconversion solutions in wireless infrastructure where size and weight are significant design factors.
