HMC531LP5

Overview

The HMC531LP5 is a monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It operates within a frequency range of 13.6 GHz to 14.9 GHz and features an integrated half-frequency output. The device requires a tuning voltage between 2 VDC and 13 VDC and functions with a supply voltage of 4.75 V to 5.25 V. It draws a maximum current of 300 mA and exhibits a phase noise of -110 dBc/Hz at a 100 kHz offset. The secondary harmonic level is typically 18 dBc, with a tuning sensitivity of 6 MHz/V. The component is housed in a 32-lead QFN package measuring 5.1 mm by 5.1 mm.

Feature Summary

• Integrates a high-performance MMIC VCO with a dedicated half-frequency output for simplified system architecture.
• Eliminates the need for external resonators through on-chip design integration.
• Provides low phase noise performance suitable for demanding RF applications.

Applications

• Low noise MMIC VCO systems
• Test equipment and industrial controls
• SATCOM applications
• Military end-use systems

Procurement Notes

Verify availability status directly with authorized distributors or Analog Devices, as this part may be subject to limited supply or factory special order constraints. Confirm RoHS compliance details and moisture sensitivity levels prior to procurement. Ensure that the specific ordering suffix matches the required packaging format, such as cut tape or reel, to align with assembly line requirements. Cross-reference the manufacturer part number against official datasheets to confirm functional specifications before finalizing purchase orders.

Selection Notes

Select the HMC531LP5 when a stable source is required in the 13.6 GHz to 14.9 GHz band with integrated frequency division capabilities. Consider the 300 mA current draw and 5 V supply requirement for power budgeting. The QFN-32 package necessitates appropriate thermal management and PCB layout considerations for high-frequency performance. Evaluate the -110 dBc/Hz phase noise specification against system sensitivity requirements.

Part Context

This component belongs to the HMC531 series of MMIC VCOs from Analog Devices, formerly Hittite Microwave Corporation. The series is characterized by integrated designs that reduce external component count. The HMC531LP5 specifically targets higher frequency operations compared to other variants in the family, offering both fundamental and divided outputs in a compact surface-mount package.
