MAX2700ECM+

RF Receivers Overview

The MAX2700ECM+ is a highly integrated direct downconversion receiver designed for wireless local loop systems in the 1.8GHz to 2.1GHz band. It features a zero-IF architecture that eliminates intermediate frequency stages and SAW filters, reducing component count and board space. The device includes a low-noise amplifier with selectable gain and shutdown options, alongside a high-linearity direct I/Q downconverter. It operates on a single +2.7V to +3.3V supply within an industrial temperature range of -40°C to +85°C.

RF Receivers Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to potential counterfeit risks. Confirm package integrity and pin alignment against official datasheet specifications before integration. Check for RoHS compliance status and ensure storage conditions maintain moisture sensitivity level ratings. Validate electrical parameters against current production lot data sheets prior to final design approval.

RF Receivers Selection Notes

Select this component for applications requiring simplified RF front-end designs by removing IF filtering needs. Consider the specific 1.8GHz to 2.1GHz input frequency range compatibility. Evaluate the need for integrated LNA gain control and shutdown features versus external solutions. Assess power supply constraints against the specified +2.7V to +3.3V operating range.

RF Receivers Part Context

This part belongs to the MAX2700/MAX2701 family of direct downconversion receivers. The MAX2700 specifically targets the 1.8GHz to 2.1GHz band, while the MAX2701 covers 2.1GHz to 2.5GHz. Both share identical architectural features but differ in tuned input frequency ranges, allowing designers to select based on specific regulatory band requirements.

RF Receivers Replacement Considerations

The MAX2701ECM+ serves as a functional substitute for different frequency bands (2.1GHz to 2.5GHz). Ensure frequency compatibility when substituting. No other direct cross-model replacements are officially documented for this specific 1.8GHz to 2.1GHz configuration.
