HMC385LP4TR

Overview

The HMC385LP4TR is a surface-mount voltage-controlled oscillator (VCO) with an integrated buffer amplifier, manufactured by Analog Devices Inc. It operates within the frequency range of 2.25 GHz to 2.5 GHz. The device requires a tuning voltage range of 0 VDC to 10 VDC and draws a current of 41 mA. It delivers an output power of 4.5 dBm with a phase noise of -115 dBc/Hz and a tuning sensitivity of 2 MHz/V. Packaged in a tape-and-reel format for automated assembly, this component is designed for high-performance RF applications requiring stable oscillation.

Feature Summary

• Integrated buffer amplifier for improved signal isolation and drive capability
• Surface-mount technology construction for compact PCB integration
• Wide tuning voltage range supporting flexible frequency control schemes

Applications

• Wireless communication systems operating in the S-band
• Local oscillator sources for upconversion and downconversion mixers
• Test and measurement equipment requiring stable RF signals

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering. Validate part marking against datasheet specifications to prevent counterfeit substitution during procurement.

Selection Notes

Select this component when a fixed frequency range near 2.4 GHz is required with integrated buffering. Compare phase noise performance against alternative VCOs if strict spectral purity is critical. Consider the 41 mA current consumption relative to system power budgets. Verify that the 24-pin QFN package dimensions fit the available board space constraints.

Part Context

This part belongs to the HMC385 series of voltage-controlled oscillators from Analog Devices. It shares the same core architecture as the leaded HMC385LP4 variant but utilizes a tape-and-reel packaging format suitable for high-volume surface-mount production lines. The series is characterized by silicon-based MMIC technology optimized for RF stability.

Replacement Considerations

The HMC385LP4 is the non-tray equivalent offering identical electrical characteristics. No other specific substitute part numbers are publicly confirmed in the provided documentation.
