HMC511LP5E

Overview

The HMC511LP5E is a monolithic Voltage Controlled Oscillator (VCO) from Analog Devices, designed for microwave and millimeter-wave applications. It operates in the frequency range of 9.05 GHz to 10.15 GHz with a center frequency of 9.6 GHz. The device features dual outputs at Fo and Fo/2, providing frequency agility without an external resonator. It requires a supply voltage between 4.75 V and 5.25 V and a tuning voltage range of 2 VDC to 13 VDC. The typical phase noise is -115 dBc/Hz, and the power output is +9 dBm minimum. The unit is housed in a QFN-32 package and supports surface mount installation.

Feature Summary

• Dual output capability providing both fundamental frequency (Fo) and divided frequency (Fo/2) signals for flexible system integration.
• Monolithic design eliminates the need for external resonators, simplifying circuit layout and reducing component count.
• Integrated frequency divider functionality allows for direct generation of lower frequency signals alongside the primary oscillation.

Applications

• Microwave communication systems requiring stable local oscillator sources
• Millimeter-wave radar modules for sensing and detection
• Test and measurement equipment needing precise frequency synthesis

Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or factory special order constraints. Confirm that the specific suffix LP5E matches the required RoHS compliance and moisture sensitivity levels for your assembly process. Ensure the ordering quantity aligns with the manufacturer's packaging specifications to avoid discrepancies in delivery.

Selection Notes

Select this component when a wide tuning range within the Ka-band is required alongside a secondary harmonic output. Consider the 300 mA current rating and thermal management requirements associated with the QFN-32 package. Evaluate the -115 dBc/Hz phase noise specification against system sensitivity requirements to ensure adequate signal purity for the intended application environment.

Part Context

This device belongs to the HMC511 series of Voltage Controlled Oscillators manufactured by Analog Devices. It is engineered for high-performance RF applications where compact size and integrated functionality are critical. The series typically targets industries demanding reliable microwave signal generation with minimal external support components.
