HMC505LP4

Overview

The HMC505LP4 is a Voltage Controlled Oscillator (VCO) from Analog Devices, operating within the 6.8 GHz to 7.4 GHz frequency range. It features an integrated buffer amplifier and is housed in a 24-pin QFN package measuring 4.1 mm x 4.1 mm x 1 mm. The device requires a supply voltage between 2.75 V and 3.25 V, drawing approximately 90 mA of current. It delivers an output power of 11 dBm with a tuning sensitivity of 20 MHz/V using a control voltage range of 1 VDC to 11 VDC. Phase noise performance reaches -106 dBc/Hz at specific offsets. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated buffer amplifier for improved signal integrity
• Wide tuning range with high linearity sensitivity
• Compact surface-mount QFN packaging for space-constrained designs

Applications

• Wireless communication systems requiring stable local oscillators
• Test and measurement equipment needing precise frequency generation
• Satellite communication uplink/downlink modules

Procurement Notes

Verify the specific suffix and tape/reel configuration against your manufacturing requirements. Confirm RoHS compliance status as indicated in official documentation. Ensure compatibility with your PCB footprint design, specifically the 24-pin QFN thermal pad requirements. Check for any regional distribution restrictions or limited availability notices before finalizing procurement plans.

Selection Notes

Select this component when a wide tuning range and integrated buffering are required without external amplifiers. Consider the 24-pin QFN form factor for compact board layouts. Evaluate the phase noise specifications against system jitter tolerance requirements. Ensure the 1-11 V tuning voltage aligns with available control circuitry capabilities.
