HMC515LP5E

Overview

The HMC515LP5E is a Voltage Controlled Oscillator (VCO) manufactured by Analog Devices Inc., designed for surface-mount applications in the QFN-32 package. It operates within a frequency range of 11.5 GHz to 12.5 GHz, utilizing an internal frequency doubler and divide-by-4 circuitry. The device requires a supply voltage between 4.75 V and 5.25 V, with a tuning voltage range of 2 VDC to 13 VDC. Key electrical specifications include a phase noise of -110 dBc/Hz, a tuning sensitivity of 6 MHz/V, and a secondary harmonic suppression of 24 dBc. The component draws a current rating of 240 mA and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates frequency doubling and divide-by-4 functionality within a single monolithic microwave integrated circuit.
• Provides high spectral purity through optimized phase noise performance suitable for demanding RF systems.
• Features a compact QFN-32 surface-mount package designed for efficient PCB layout and thermal management.

Applications

• Point-to-point microwave radio links
• Local oscillator sources for upconversion and downconversion mixers
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'P5E' against the manufacturer's official documentation to ensure correct pinout and packaging configuration. Confirm RoHS compliance status directly with the supplier or via the latest datasheet revision history. Check for any recent product change notifications that may affect lead times or material composition. Ensure the ordering quantity matches the available reel or cut tape options specified in the procurement catalog.

Selection Notes

Select this component when a stable source in the 11.5–12.5 GHz range is required with integrated frequency scaling. Compare the 240 mA current consumption against system power budgets relative to other VCOs in the HMC51x series. Evaluate the -110 dBc/Hz phase noise specification against system sensitivity requirements. Ensure the 2 VDC to 13 VDC tuning voltage range aligns with the available control voltage outputs in the design.

Part Context

The HMC515LP5E belongs to the HMC515 family of MMIC VCOs produced by Analog Devices. These components are engineered for high-performance wireless infrastructure and radar applications. The family utilizes advanced semiconductor processes to deliver consistent gain and noise characteristics. This specific part number represents the lead-free, halogen-free variant housed in a standard QFN-32 footprint.

Replacement Considerations

The HMC515LP5ETR serves as the reel-packaged equivalent of the HMC515LP5E cut-tape version. Both parts share identical electrical specifications and pinouts. Verify package compatibility if substituting with other HMC51x series variants, as frequency ranges differ significantly between models like the HMC510 and HMC512.
