HMC506LP4TR

Overview

The HMC506LP4TR is a Voltage Controlled Oscillator (VCO) from Analog Devices Inc., operating within the 7.8 GHz to 8.7 GHz frequency range. It features an integrated buffer amplifier and is housed in a compact 24-lead QFN package measuring 4.1 mm by 4.1 mm. The device requires a supply voltage between 2.75 V and 3.25 V, drawing a typical current of 88 mA. It delivers an output power of 14 dBm with a tuning sensitivity of 78 MHz/V across a 1 VDC to 11 VDC control voltage range. Phase noise performance is specified at -103 dBc/Hz.

Feature Summary

• Integrated buffer amplifier for improved signal isolation and drive capability
• Compact surface-mount QFN-24 package design for space-constrained applications
• Wide tuning voltage range supporting flexible frequency synthesis integration

Applications

• VSAT communication systems
• Wireless local loop infrastructure
• Point-to-point microwave links

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the part number suffix matches the specific reel or cut tape configuration required for your assembly process. Ensure compliance with RoHS directives as indicated in the official datasheet documentation before final procurement decisions.

Selection Notes

Select this component when high output power and moderate phase noise are prioritized over ultra-low noise performance. The integrated buffer simplifies circuit design by eliminating external amplification stages. Consider the 78 MHz/V pushing factor when designing the voltage control loop stability for the target application environment.

Part Context

This model belongs to the HMC506 series of monolithic VCOs designed for Ku-band applications. It shares the same QFN-24 footprint and operational voltage characteristics with other variants in the family, differing primarily in center frequency and output power specifications. The series targets robust performance in commercial wireless infrastructure environments.

Replacement Considerations

Direct substitutes include the HMC506LP4ETR and HMC506LP4. Verify pin compatibility and electrical parameter alignment with the original design requirements before implementing any cross-reference components.
