MAX2750EUA

Overview

The MAX2750EUA is a monolithic voltage-controlled oscillator (VCO) designed for ISM band applications, operating within the 2.4 GHz to 2.5 GHz frequency range. It features an on-chip tank circuit and requires a supply voltage between 2.7 V and 5.5 V. The device delivers -3 dBm output power with a tuning voltage range of 400 mVDC to 2.4 VDC. Key electrical specifications include a phase noise of -235 dBc/Hz, a push of 1.3 MHz/V, and a current consumption of 21 mA. It is housed in an 8-pin uMAX package.

Feature Summary

• Integrates a fully self-contained voltage-controlled oscillator with an on-chip tank circuit for compact design
• Optimized for ISM band operation with high spectral purity characterized by low phase noise
• Provides stable output power across a wide supply voltage range without external components

Applications

• Wireless LAN modules
• Bluetooth transceivers
• ISM band communication systems

Procurement Notes

Verify the specific suffix of the part number when ordering, as variants such as MAX2750EUA+T indicate tape-and-reel packaging while others may differ. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant matches the required supply chain constraints and lead times available from authorized distributors. Cross-reference the datasheet revision to guarantee compatibility with existing design specifications.

Selection Notes

Select this component for designs requiring a compact, low-power VCO solution in the 2.4 GHz ISM band. The integrated tank circuit reduces external component count compared to discrete solutions. Evaluate the tuning voltage range against the control interface capabilities of the system microcontroller or synthesizer. Consider the thermal performance and package size relative to the PCB layout constraints of the target application.

Part Context

The MAX2750 belongs to a family of RF oscillators from Analog Devices / Maxim Integrated. It serves as a core frequency generation element in wireless connectivity chips.
