HMC737LP4E

Overview

The HMC737LP4E is a monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It operates within a frequency range of 14.9 GHz to 15.5 GHz and features dual outputs, including a standard output and a divide-by-2 half-frequency output. The device requires a supply voltage between 4.75 V and 5.25 V and draws a current of 180 mA. It utilizes a tuning voltage range from 1 VDC to 13 VDC with a sensitivity of 24 MHz/V. The component is housed in a QFN-24 surface-mount package.

Feature Summary

• Integrates dual output paths providing both standard and divided-by-two frequency signals for flexible system integration.
• Utilizes HBT technology to achieve low phase noise performance suitable for high-frequency applications.
• Designed as a general-purpose RF MMIC VCO with a compact surface-mount footprint.

Applications

• Wireless communication systems requiring local oscillation
• Test and measurement equipment
• Satellite communication subsystems

Procurement Notes

Verify the exact suffix and package type when ordering, as availability may vary. Confirm that the intended application supports the specific frequency range and power requirements. Check for any recent product change notices or end-of-life announcements from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a dual-output VCO is required at approximately 15 GHz. Ensure the design accommodates the 180 mA current draw and the 4.75 V to 5.25 V supply range. Consider the QFN-24 package dimensions for PCB layout constraints compared to other packages in the series.

Part Context

This part belongs to the HMC73x series of MMIC VCOs from Analog Devices. It shares similar tuning characteristics and packaging with related models like the HMC736 and HMC738, differing primarily in operating frequency and output configuration. The series is designed for high-performance RF applications.

Replacement Considerations

Direct substitutes include the HMC736LP4E for lower frequency operations around 14.5-15.0 GHz. Verify pin compatibility and thermal requirements when considering alternative parts from the same family.
