HMC430LP4E

Overview

The HMC430LP4E is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator (VCO) from Analog Devices, operating within the 5.0 GHz to 5.5 GHz frequency range. It features an integrated buffer amplifier and resonators. The device requires a supply voltage between 2.75 V and 3.25 V, with a typical current consumption of 34 mA. Output power is specified at 2 dBm, utilizing a tuning voltage range of 0 VDC to 10 VDC. It is housed in a compact QFN-24 surface-mount package.

Feature Summary

• Integrates negative resistance generation and resonators for self-sustained oscillation
• Includes an on-chip buffer amplifier to isolate load variations from the core oscillator
• Utilizes GaAs InGaP Heterojunction Bipolar Transistor technology for high-frequency performance

Applications

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

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure storage conditions align with semiconductor handling standards to prevent moisture sensitivity damage prior to reflow soldering.

Selection Notes

Select this component when a fixed frequency range near 5 GHz is required without external tuning circuitry complexity. Consider the integrated buffer amp for simplified impedance matching. Evaluate thermal management needs due to the small QFN-24 footprint and ensure the control voltage source supports the 0-10 VDC input range.

Part Context

This part belongs to the Hittite Microwave (now Analog Devices) portfolio of RF MMICs. It represents a specialized solution for microwave applications where size and integration are critical. The LP4E suffix typically denotes a lead-free, halogen-free variant compliant with environmental directives, packaged in a standard land grid array format suitable for automated assembly.

Replacement Considerations

Direct substitutes may include other Analog Devices VCOs in the same family with compatible pinouts and frequencies, such as the HMC429LP4E for slightly lower frequencies. Verify that any replacement matches the QFN-24 package dimensions and electrical specifications exactly.
