HMC416LP4E

Overview

The HMC416LP4E is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator (VCO) from Analog Devices, operating in the 2.75 GHz to 3.0 GHz frequency range. It features an integrated buffer amplifier and resonators within a compact QFN-24 package. The device operates on a supply voltage between 2.75 V and 3.25 V, drawing a typical current of 42 mA. It delivers an output power of 4.5 dBm with a tuning voltage range of 0 VDC to 10 VDC. Key performance metrics include a phase noise of -114 dBc/Hz and a pushing coefficient of -1 MHz/V. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates negative resistance and resonators for self-contained oscillation
• Includes an internal buffer amplifier for signal isolation
• Utilizes GaAs InGaP HBT technology for high performance

Applications

• Wireless communication systems
• Local oscillator sources in RF receivers
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'E' against official Analog Devices documentation to confirm RoHS compliance status, as some listings indicate non-compliance while others suggest detailed verification is required. Confirm the package type is QFN-24 with exposed pad. Ensure the datasheet version matches the production lot for accurate electrical specifications. Check for any obsolescence notices or limited availability warnings directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a fixed-frequency source near 3 GHz is required with integrated buffering. The QFN-24 package suits space-constrained PCB layouts. Verify that the 0-10 V tuning range aligns with available control voltages. Consider the 42 mA current draw for power budget calculations. Ensure thermal management supports the -40°C to +85°C operational range for the intended environment.

Part Context

This part belongs to the HMC416 series of MMIC VCOs. It shares architectural similarities with other members like the HMC416LP4 but may differ in environmental compliance or specific trim values. The series utilizes GaAs HBT technology. Other variants in the family cover different frequency bands, such as the HMC391 series which operates at higher frequencies around 4 GHz.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public data. The HMC416LP4 is a related variant; verify if it meets all functional and regulatory requirements. Cross-reference pinouts and electrical specs with Analog Devices application notes for potential drop-in alternatives.
