HMC389LP4E

Overview

The HMC389LP4E is a monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It operates within the frequency range of 3.35 GHz to 3.55 GHz and features an integrated buffer amplifier. The device requires a supply voltage between 2.75 V and 3.25 V, drawing a current of 46 mA. It utilizes a tuning voltage range of 0 VDC to 10 VDC with a sensitivity of 3 MHz/V. Key performance metrics include an output power of 4.7 dBm and phase noise of -115 dBc/Hz. The component is housed in a QFN-24 package measuring 4.1 mm x 4.1 mm x 1 mm and supports operation from -40°C to +85°C.

Feature Summary

• Integrates a voltage-controlled oscillator core with a dedicated buffer amplifier for signal isolation.
• Utilizes MMIC technology to provide compact form factor and consistent RF performance.
• Features analog voltage tuning capability across a defined DC control range.

Applications

• Wireless communication systems requiring stable local oscillation
• Test and measurement instrumentation equipment
• Satellite communication transceivers

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status via official documentation prior to integration. Check for discontinuance notices or lifecycle changes as the product may be subject to limited availability or end-of-life status. Ensure storage conditions meet specified environmental requirements to maintain reliability.

Selection Notes

Select this component when a fixed frequency band around 3.4 GHz is required with integrated buffering. Consider the specific tuning linearity and phase noise specifications against system requirements. Evaluate the QFN-24 package thermal characteristics for PCB layout. Compare against other MMIC VCOs if variable frequency ranges or different output power levels are needed.

Part Context

The HMC389 series represents Analog Devices' portfolio of high-performance MMIC oscillators designed for RF applications. These components integrate passive and active elements on a single semiconductor die to minimize size and parasitic effects. The LP4E suffix typically denotes a specific tape-and-reel packaging configuration suitable for surface-mount assembly processes.

Replacement Considerations
