MAX2623EUA-T

Overview

The MAX2623EUA-T is a monolithic voltage-controlled oscillator (VCO) from Analog Devices, manufactured by Maxim Integrated. It operates within a frequency range of 885 MHz to 950 MHz, with a center frequency of 917.5 MHz. The device supports a supply voltage between 2.7 V and 5.5 V and utilizes a tuning voltage range of 0.4 V to 2.4 V. Key electrical specifications include a maximum supply current of 11.5 mA, a typical second harmonic level of -27 dBc, and a phase noise of -101 dBc/Hz. The component is housed in an 8-pin uMAX surface-mount package.

Procurement Notes

Verify the specific ordering suffix (+T) against the manufacturer's official documentation to ensure correct reel quantity and tape-and-reel configuration. Confirm that the part number matches the exact frequency range and package type required for the design. Cross-reference the datasheet revision date to ensure compliance with current manufacturing standards and pinout definitions before finalizing procurement orders.

Selection Notes

Select this component when a self-contained VCO solution is needed for the 885-950 MHz band. Consider the 11.5 mA current consumption and -101 dBc/Hz phase noise performance relative to system requirements. Ensure the 0.4 V to 2.4 V tuning voltage range aligns with the available control voltage sources in the application circuit.

Part Context

This part belongs to the MAX2623 family of monolithic voltage-controlled oscillators designed by Maxim Integrated. These devices are engineered to provide stable frequency generation in RF applications. The MAX2623 series typically offers integrated passive components to minimize external parts count and board space.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitute part numbers. Do not assume functional compatibility with other VCO models without verifying pinout, frequency range, and electrical specifications.
