HMC733LC4BTR

Overview

The HMC733LC4BTR is a wideband monolithic microwave integrated circuit voltage-controlled oscillator (VCO) operating in the W-band frequency range of 10 GHz to 20 GHz. It integrates an on-chip buffer amplifier for improved output drive capability. The device operates with 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, delivering an output power of 3 dBm. Key performance metrics include a phase noise of -60 dBc/Hz, second harmonic suppression of -20 dBc, and a tuning sensitivity of 90 MHz/V. The component is housed in a compact QFN-24 package measuring 4.1 mm by 4.1 mm.

Feature Summary

• Integrates a wideband VCO core with an on-chip buffer amplifier for enhanced signal integrity
• Operates within the W-band spectrum covering 10 GHz to 20 GHz frequencies
• Provides stable output power with low phase noise characteristics suitable for high-frequency applications

Applications

• Radar systems requiring high-frequency signal generation
• Point-to-point wireless communication links
• Test and measurement instrumentation equipment

Procurement Notes

Verify the specific suffix LC4BTR against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with moisture-sensitive handling protocols as indicated by the MSL rating. Confirm that the required tuning voltage range aligns with system control circuits before integration.

Selection Notes

Select this component when a wideband W-band solution is required without external buffering. Compare the 10-20 GHz range against narrower alternatives like the HMC732 series if lower frequencies suffice. Evaluate the 70 mA current consumption against power budget constraints and ensure the QFN-24 thermal pad design supports adequate heat dissipation for the intended operating temperature range.

Part Context

This part belongs to the HMC733 family of wideband MMIC VCOs manufactured by Analog Devices. It shares architectural similarities with other members of the series but is distinctively tuned for the higher W-band frequency range. The inclusion of the buffer amplifier differentiates it from bare VCO cores, simplifying PCB layout by reducing the need for additional discrete amplification stages.
