MAX275BEPP+

Overview

The MAX275BEPP+ is a low-power, quadrature signal processor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates an analog front-end for direct conversion of RF signals to baseband. The device operates on a single +3V supply and features a 16-pin PDIP package. Key electrical parameters include a center frequency range of 10MHz to 45MHz, a programmable 3dB bandwidth from 10kHz to 200kHz, and a -90dBc image rejection ratio. It supports IF frequencies up to 10.7MHz.

Feature Summary

• Integrates quadrature modulator/demodulator and active filters
• Direct down-conversion from RF to baseband
• Programmable bandwidth and center frequency control

Applications

• GPS receivers
• ISM band transceivers
• Low-cost FM radio receivers

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices prior to procurement. Ensure storage conditions meet specified humidity sensitivity levels to prevent package damage during assembly.

Selection Notes

Select this component when designing systems requiring direct RF-to-baseband conversion without external mixers. Compare against the MAX274 variant if differential outputs are required instead of single-ended. Verify that the operating temperature range meets system environmental requirements.

Part Context

This part belongs to the MAX274/MAX275 family of quadrature signal processors. It shares architectural similarities with other Maxim integrated RF front-ends but is distinct in its specific pinout and output configuration designed for cost-sensitive applications.

Replacement Considerations

The MAX274BEPP+ is a functional substitute within the same family, offering differential outputs instead of single-ended. Verify pin compatibility and output stage requirements before substitution.
