HMC737LP4ETR

Overview

The HMC737LP4ETR is an MMIC Voltage Controlled Oscillator (VCO) manufactured by Analog Devices Inc. It operates within a frequency range of 23.8 GHz to 26.8 GHz and includes an integrated RF/2 divider and a divide-by-16 counter. The device features a tuning voltage range of 1 VDC to 13 VDC with a push of 24 MHz/V. It draws a current rating of 180 mA and exhibits a phase noise type of -105 dBc/Hz. Packaged in a 24-lead QFN, it is designed for high-frequency applications requiring stable oscillation.

Feature Summary

• Integrates a half-frequency output via an internal RF/2 divider
• Includes a programmable divide-by-16 counter for frequency synthesis
• Utilizes HBT technology for low-noise performance

Applications

• Wireless communication systems
• Test and measurement equipment
• Point-to-point microwave links

Procurement Notes

Verify the specific suffix LP4ETR against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with required supply voltages and tuning ranges before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the manufacturer's latest datasheet or compliance declaration.

Selection Notes

Select this component when a compact solution combining VCO, divider, and counter functions is required. Consider the 24-QFN package for surface-mount assembly constraints. Evaluate the 180 mA current draw against power budget limitations. Verify that the 1 VDC to 13 VDC tuning range aligns with available control circuitry. Assess phase noise requirements against the specified -105 dBc/Hz metric.
