HMC509LP5ETR

Overview

The HMC509LP5ETR is a dual-band Voltage Controlled Oscillator (VCO) manufactured by Analog Devices Inc., designed for high-performance RF applications. It operates in two frequency bands: 3.9 GHz to 4.4 GHz and 7.8 GHz to 8.8 GHz, with center frequencies of 4.15 GHz and 8.3 GHz respectively. The device features an integrated Fo/2 output at the lower band. It utilizes a tuning voltage range of 2 VDC to 13 VDC and requires a supply voltage between 4.75 V and 5.25 V. Key electrical parameters include a typical phase noise of -115 dBc/Hz, a tuning sensitivity of 10 MHz/V, and a maximum current consumption of 270 mA. The secondary harmonic suppression is typically 10 dBc. The component is housed in a 32-VFQFN package measuring 5.1 mm x 5.1 mm with a height of 1 mm.

Feature Summary

• Dual-band operation covering 3.9-4.4 GHz and 7.8-8.8 GHz ranges
• Integrated second harmonic output (Fo/2) at the lower frequency band
• High spectral purity with typical phase noise of -115 dBc/Hz
• Surface-mount QFN-32 package design for compact integration

Applications

• Wireless communication systems requiring dual-band frequency generation
• Test and measurement equipment needing stable RF sources
• Point-to-point microwave radio links
• Satellite communication ground stations

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Check for moisture sensitivity level (MSL 3) handling requirements during storage and reflow soldering. Confirm that the specific revision matches the required datasheet specifications. Ensure proper ESD protection protocols are followed during handling due to the sensitive nature of RF integrated circuits. Validate packaging integrity to prevent damage to the exposed thermal pad.

Selection Notes

Select this component when dual-band functionality within the specified frequency ranges is required without external dividers. Consider the 270 mA current draw for power budget calculations. Evaluate the -115 dBc/Hz phase noise against system jitter requirements. The integrated Fo/2 output simplifies circuit design for the lower band. Ensure the control voltage range of 2-13 VDC aligns with available tuning supplies. The QFN-32 package necessitates adequate thermal management on the PCB.

Part Context
