HMC505LP4ETR

Overview

The HMC505LP4ETR is a voltage-controlled oscillator (VCO) from Analog Devices, designed for surface-mount applications. It operates within a frequency range of 6.8 GHz to 7.4 GHz and delivers an output power of 11 dBm. The device requires a supply voltage between 2.75 V and 3.25 V, with a typical current rating of 90 mA. Frequency tuning is achieved via a control voltage ranging from 1 VDC to 11 VDC, providing a tuning sensitivity of 20 MHz/V. It features a phase noise specification of -106 dBc/Hz and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated buffer amplifier for direct signal output
• Narrow-band operation optimized for specific RF bands
• Low-power consumption design suitable for portable systems

Applications

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

Procurement Notes

Verify the exact ordering suffix and package variant when sourcing, as distribution channels may list different reel quantities or tape specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability for this component can be subject to change. Ensure that the procurement documentation matches the specific part number HMC505LP4ETR to avoid confusion with evaluation boards or non-TR variants.

Selection Notes

Select this component for designs requiring a stable, narrow-band source in the Ka-band range. Consider the 24-VFQFN exposed pad package for thermal management and PCB space constraints. Evaluate the 11 dBm output power against downstream mixer or amplifier requirements to determine if additional gain stages are necessary. Verify that the 1 VDC to 11 VDC tuning range aligns with the available control voltage sources in the system architecture.

Part Context
