HMC384LP4

Overview

The HMC384LP4 is a Voltage Controlled Oscillator (VCO) from Analog Devices Inc., designed for surface-mount applications. It operates within a frequency range of 2.05 GHz to 2.25 GHz and features an integrated buffer amplifier. The device requires a supply voltage between 2.75 V and 3.25 V, with a typical operating current of 41 mA. Output power is specified at 3.5 dBm, while phase noise reaches -112 dBc/Hz. The tuning voltage range spans 0 VDC to 10 VDC, providing a push of 5 MHz/V. Encased in a QFN-24 package measuring 4.1 mm by 4.1 mm by 1 mm, it supports operation from -40°C to +85°C.

Feature Summary

• Integrated buffer amplifier for direct signal output
• Surface-mount QFN-24 packaging for compact integration
• Wide tuning voltage range supporting flexible frequency control

Applications

• Wireless communication systems requiring stable local oscillators
• Test and measurement equipment needing precise frequency generation
• Satellite navigation receiver front-ends

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status via official datasheets before procurement. Ensure storage conditions align with manufacturer specifications to maintain performance integrity. Cross-reference part numbers carefully to avoid substitution errors during sourcing.

Selection Notes

Select this VCO when a fixed frequency range near 2.1 GHz is required without external tuning circuitry complexity. Consider the integrated buffer for simplified board layout compared to discrete solutions. Evaluate thermal management needs given the 41 mA current draw and QFN-24 thermal pad requirements. Compare phase noise specifications against system sensitivity requirements.
