HMC505LP4E

Overview

The HMC505LP4E is a voltage-controlled oscillator (VCO) with an integrated buffer amplifier, manufactured by Analog Devices Inc. It operates within the frequency range of 6.8 GHz to 7.4 GHz and is housed in a 24-lead QFN package measuring 4 mm x 4 mm x 1 mm. The device requires a supply voltage between 2.75 V and 3.25 V, drawing approximately 90 mA. It features a tuning voltage range of 1 VDC to 11 VDC with a sensitivity of 20 MHz/V. Key performance metrics include an output power of 11 dBm and a phase noise of -106 dBc/Hz at a specific offset.

Feature Summary

• Integrates a voltage-controlled oscillator core with a dedicated buffer amplifier for signal isolation.

Applications

• VSAT communication systems
• Point-to-point microwave links
• Satellite navigation receivers

Procurement Notes
