HMC508LP5ETR

Overview

The HMC508LP5ETR is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator (VCO) manufactured by Analog Devices Inc. It operates in the frequency range of 7.3 GHz to 8.2 GHz, with a half-frequency output at 3.65 GHz to 4.1 GHz. The device delivers an output power of +15 dBm and exhibits a typical phase noise of -116 dBc/Hz at a 100 kHz offset. It requires a single +5 V power supply and draws 155 mA of current. The component is housed in a 32-pin QFN-32 surface-mount package measuring 5x5 mm. It integrates the resonator, negative resistance device, and varactor diode on a single chip, eliminating the need for external matching components.

Feature Summary

• Integrates resonator, negative resistance device, and varactor diode on a single chip for compact design
• Provides dual outputs including fundamental frequency and half-frequency signals
• Delivers high phase noise performance across temperature, shock, and process variations
• Requires no external matching elements due to integrated monolithic structure

Applications

• VSAT radio systems
• Point-to-point and point-to-multipoint radio links
• Test equipment and industrial control systems
• Military end-use applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the received unit matches the specific HMC508LP5ETR designation, as variants may exist within the family. Check for proper ESD protection during handling and storage. Ensure that the supply voltage and tuning voltage ranges align with system requirements before integration. Review the latest datasheet for any updates regarding pin configuration or thermal characteristics.

Selection Notes

Select this VCO when a stable, low-phase-noise source is required for Ku-band applications. The integrated design simplifies PCB layout by removing the need for external passive components. Consider the 5V supply requirement and 155mA current draw for power budgeting. The dual-output capability allows for flexible signal routing without additional dividers. Evaluate thermal management needs given the QFN-32 package size and power dissipation.
