HMC732LC4BTR-R5

Overview

The HMC732LC4BTR-R5 is a wideband voltage-controlled oscillator (VCO) with an integrated buffer amplifier, manufactured by Analog Devices Inc. It operates within a frequency range of 6 GHz to 12 GHz and is housed in a 24-lead CSMT package measuring 4x4 mm. The device requires a supply voltage between 4.75 V and 5.25 V, drawing a typical current of 57 mA. It features a tuning voltage range from 0 VDC to 23 VDC with a sensitivity of -85 MHz/V. Key performance metrics include an output power of 1 dBm, phase noise of -65 dBc/Hz, and second harmonic suppression of -12 dBc. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a wideband VCO core with a dedicated buffer amplifier for signal isolation.
• Provides stable RF output generation across the 6 GHz to 12 GHz spectrum.
• Utilizes a compact surface-mount QFN package for efficient PCB layout.

Applications

• Radar systems requiring precise frequency synthesis
• Wireless communication infrastructure components
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix R5 against official Analog Devices documentation to confirm reel specifications and tape-and-reel dimensions. Ensure compatibility with standard SMD reflow processes given the moisture sensitivity level. Cross-reference the part number with authorized distributors to confirm current availability status, as supply constraints may affect lead times. Confirm that the ordering configuration matches the required packaging format for automated assembly lines.

Selection Notes

Select this component when a wide tuning range and integrated buffering are required for W-band applications. Consider the 57 mA current consumption and 5 V supply requirement for power budgeting. Evaluate the -65 dBc/Hz phase noise specification against system jitter requirements. Compare the 4x4 mm footprint against available board space constraints relative to alternative VCO solutions in the same frequency band.

Part Context

This part belongs to the HMC732 series of wideband VCOs designed for high-frequency RF applications. It shares the same functional architecture and package outline with variants such as HMC732LC4B and HMC732LC4BTR, differing primarily in packaging quantity and reel configuration. The series is characterized by monolithic integration of the oscillator and buffer stages to minimize external component count and improve performance consistency.

Replacement Considerations

HMC732LC4B and HMC732LC4BTR are functionally equivalent parts within the same family. Verify if the specific reel size or cut-tape configuration of the R5 suffix is critical for manufacturing equipment before substituting with other suffixes.
