HMC735LP5E

Overview

The HMC735LP5E is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator (VCO) operating from 10.5 to 12.2 GHz. It features a divide-by-4 output at 2.625 to 3.05 GHz with +17 dBm power. Phase noise is -100 dBc/Hz at 100 kHz offset. It requires no external resonators or matching components, operates on a +5V supply, and draws 240 mA. The device is housed in a 5x5 mm QFN-32 package.

Feature Summary

• Integrates resonators, negative resistance devices, and varactor diodes for monolithic stability
• Provides dual outputs including a standard frequency and a divide-by-4 signal
• Eliminates need for external resonators or matching components
• Prescaler function can be disabled to conserve current when not required

Applications

• Point-to-Point/Multi-Point Radio systems
• SATCOM applications
• Test Equipment & Industrial Controls
• Military End-Use equipment

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's datasheet to confirm RoHS compliance status, as legacy documentation may list leaded variants. Confirm the QFN-32 package dimensions match your PCB footprint requirements. Check for moisture sensitivity levels if the component has been stored without proper dry packing conditions.

Selection Notes

Select this VCO for designs requiring high phase noise performance and integrated frequency division without external passive components. The fixed 10.5–12.2 GHz range suits specific microwave bands. Consider the 240 mA current draw for power budgeting. Ensure the control voltage range of 1–13 VDC is compatible with the system's tuning interface.

Part Context

This component belongs to the HMC735 series of MMIC VCOs manufactured by Analog Devices Inc. It utilizes GaAs InGaP HBT technology to achieve robust performance across temperature and process variations. The series is designed for high-frequency wireless communication applications where size and integration are critical constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit layouts before considering alternative VCOs from other manufacturers.
