MAX2751EUA+T

Overview

The MAX2751EUA+T is a monolithic voltage-controlled oscillator (VCO) designed for ISM band applications. It operates within a frequency range of 2.12 GHz to 2.26 GHz and requires a supply voltage of 2.7 V to 5.5 V. The device features an on-chip tank circuit, eliminating the need for external inductors. Key electrical specifications include a tuning voltage range of 400 mVDC to 2.4 VDC, a typical current consumption of 15.2 mA, and an output power of -3 dBm. It exhibits a phase noise of -125 dBc/Hz at a 1 MHz offset and a push factor of 1.3 MHz/V. The component is housed in an 8-uMAX package.

Feature Summary

• Integrates an on-chip tank circuit to minimize external component requirements
• Designed specifically for ISM band wireless applications
• Operates with a wide single-supply voltage range

Applications

• ISM band wireless communication systems
• RF transceiver local oscillators
• Wireless sensor networks

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as '+'. Ensure the 8-uMAX package dimensions match your PCB footprint constraints. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines. Validate that the operating temperature range meets your environmental requirements.

Selection Notes

Select this component for designs requiring a compact, low-component-count VCO solution. Consider the -3 dBm output power level for direct coupling or amplifier integration needs. Evaluate the 15.2 mA current draw against system power budgets. Compare the 2.12–2.26 GHz tuning range against required channel spacing. Assess the -125 dBc/Hz phase noise performance against system sensitivity requirements.

Part Context

The MAX2751 belongs to the MAX2750-52 family of monolithic VCOs from Analog Devices/Maxim Integrated. These devices are optimized for cost-sensitive, space-constrained RF applications. The family shares similar architectural features, differing primarily in center frequency and tuning ranges. This series supports rapid development of ISM band transceivers.

Replacement Considerations

The MAX2752EUA+ is a documented substitute within the same product family. Verify frequency range compatibility as the MAX2752 operates between 2.025 GHz and 2.165 GHz. Ensure pinout and package dimensions remain identical for direct replacement.
