HMC384LP4ETR

Overview

The HMC384LP4ETR is a Voltage Controlled Oscillator (VCO) from Analog Devices, operating in the 2.05 GHz to 2.25 GHz frequency range. It features an integrated buffer amplifier and utilizes a QFN-24 surface-mount package. The device requires a tuning voltage of 0 VDC to 10 VDC and operates on a supply voltage between 2.75 V and 3.25 V. Key electrical specifications include a typical phase noise of -112 dBc/Hz, an output power of 3.5 dBm, and a current consumption of 41 mA. It supports a tuning slope of 5 MHz/V and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a buffer amplifier for direct signal driving capabilities
• Provides low phase noise performance suitable for narrowband applications
• Utilizes a compact surface-mount QFN-24 package design

Applications

• Narrowband communication systems
• Frequency synthesis circuits

Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific suffix 'ETR' indicates reel packaging if required by assembly processes. Ensure compatibility with the specified 2.75 V to 3.25 V supply range and 0 VDC to 10 VDC tuning voltage requirements during integration. Check for any recent product change notices regarding manufacturing locations or materials.

Selection Notes

Select this component when a stable, low-phase-noise source is needed within the 2.05–2.25 GHz band. Consider the integrated buffer amplifier if isolation or drive capability is required without additional external stages. Evaluate the QFN-24 footprint against available PCB space. Compare power consumption and tuning linearity against alternative VCOs if system efficiency or frequency accuracy is critical.
