HMC386LP4E

Overview

The HMC386LP4E is a surface-mount voltage-controlled oscillator (VCO) from Analog Devices, operating within the 2.6 GHz to 2.8 GHz frequency range. It features an integrated buffer amplifier and utilizes a QFN-24 package with dimensions of 4.1 mm x 4.1 mm x 1 mm. The device requires a supply voltage between 2.75 V and 3.25 V, drawing approximately 35 mA to 40 mA. It supports a tuning voltage range of 0 VDC to 10 VDC with a push of -2 MHz/V. Key performance metrics include a typical output power of 5 dBm, phase noise of -114 dBc/Hz, and operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a buffer amplifier for improved signal isolation and drive capability
• Utilizes a compact QFN-24 surface-mount package for efficient PCB layout
• Provides stable oscillation across a wide industrial temperature range

Applications

• Wireless communication systems requiring local oscillator signals

• Radar systems utilizing microwave frequency synthesis

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status via official documentation before integration. Ensure storage conditions maintain moisture sensitivity level integrity. Validate pinout alignment with design schematics to prevent installation errors during assembly processes.

Selection Notes

Select this component when a fixed frequency range near 2.7 GHz is required without external tuning complexity. Consider the integrated buffer amplifier if load isolation is critical. Evaluate the QFN-24 footprint against available board space constraints. Compare current consumption requirements against system power budgets to ensure compatibility with existing voltage regulation infrastructure.

Part Context

This part belongs to the HMC386 series of voltage-controlled oscillators designed by Analog Devices. It shares the QFN-24 package form factor with other devices in the family but differs in specific frequency ranges and internal circuit configurations. The series targets applications demanding reliable microwave signal generation in compact form factors.

Replacement Considerations

HMC386LP4ETR serves as the reel-pack equivalent of this cut-tape component. Verify that substitution maintains identical electrical specifications and thermal characteristics. Confirm that packaging differences do not impact automated pick-and-place manufacturing workflows.
