HMC531LP5TR

Overview

The HMC531LP5TR is a monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It operates within the frequency range of 13.6 GHz to 14.9 GHz and is housed in a QFN-32 surface-mount package. The device requires a supply voltage between 4.75 V and 5.25 V, with a typical current consumption of 300 mA. It features a tuning voltage range from 2 VDC to 13 VDC and offers a push performance of 6 MHz/V. The component includes internal frequency division capabilities, providing Fo/2 and Div/4 outputs. Secondary harmonic suppression is rated at 18 dBc, and phase noise is specified at -110 dBc/Hz. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates half-frequency (Fo/2) and divide-by-four (Div/4) output stages for flexible frequency synthesis applications.
• Delivers low phase noise performance suitable for high-frequency communication systems.
• Utilizes a compact QFN-32 surface-mount package for efficient PCB layout integration.

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Test and measurement instrumentation

Procurement Notes

Verify that the specific suffix TR indicates reel packaging when sourcing from distributors. Confirm RoHS compliance status as some listings may vary. Ensure the supplier provides valid traceability documentation for this Analog Devices component. Check for moisture sensitivity level requirements during storage and handling procedures before assembly.

Selection Notes

Select this component when a stable source is required in the 13.6–14.9 GHz band with integrated divided outputs. Evaluate thermal management needs due to the 300 mA current draw. Compare phase noise specifications against system jitter requirements. Ensure the control voltage range aligns with available DAC or loop filter outputs in the design.

Part Context

This part belongs to the Hittite Microwave MMIC VCO family acquired by Analog Devices. It complements other wideband oscillators like the HMC530 series, which covers lower frequencies. The LP5 designation typically denotes a lead-free, halogen-free package variant within the manufacturer's portfolio.

Replacement Considerations

HMC531LP5E is a non-tray version of the same functional device. No direct cross-manufacturer substitutes are publicly confirmed without redesigning the RF matching network.
