HMC733LC4BTR-R5

Overview

The HMC733LC4BTR-R5 is a wideband monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO) from Analog Devices, operating in the W-band frequency range of 10 GHz to 20 GHz. It integrates a buffer amplifier and is housed in a compact 24-lead QFN package measuring 4.1 mm x 4.1 mm x 1 mm. The device requires a supply voltage between 4.75 V and 5.25 V, drawing approximately 70 mA. It features a tuning voltage range from -250 mVDC to 23 VDC with a push performance of -90 MHz/V. Key electrical specifications include an output power of 3 dBm, secondary harmonic suppression of -20 dBc, and phase noise of -60 dBc/Hz.

Feature Summary

• Integrates a buffer amplifier for improved isolation and drive capability within a single surface-mount package.
• Provides wideband operation across the 10 GHz to 20 GHz W-band spectrum using MMIC technology.
• Features low phase noise characteristics suitable for high-performance radar and communication systems.

Applications

• Millimeter-wave radar systems
• Point-to-point wireless communication links
• Electronic warfare applications

Procurement Notes

Verify the specific suffix 'R5' indicates reel packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the full part number with manufacturer datasheets to confirm pinout and thermal requirements before integration.

Selection Notes

Select this component for designs requiring a wide tuning range in the W-band without external buffering. Consider the 24-QFN package for space-constrained PCB layouts. Evaluate the 70 mA current draw against power budget constraints. Verify that the required tuning voltage range aligns with available control circuitry capabilities.

Part Context

This part belongs to the HMC733 series of wideband MMIC VCOs manufactured by Analog Devices. It is designed for high-frequency applications where size and performance are critical. The device represents a solution for integrating oscillation and buffering functions into a single compact module, reducing board space compared to discrete solutions.

Replacement Considerations

Check for HMC733LC4B as a potential non-reel variant. Consult Analog Devices for updated family members with similar W-band specifications. Verify compatibility with existing PCB footprints if substituting with other QFN packages.
