General Description

The MAX2420/MAX2421/MAX2422/MAX2460/MAX2463 are highly integrated front-end ICs that provide the lowest cost solution for cordless phones and ISM-band radios operating in the 900MHz band.

All devices incorporate transmit and receive image-reject mixers to reduce filter cost.

They operate with a +2.7V to +4.8V power supply, allowing direct connection to a 3-cell battery stack.

Overview

19-1234; Rev 2; 2/99 EVFAOLLULAOTWIOSNDKAITTAMSAHNEUEATL 900MHz Image-Reject Transceivers MAX2420/MAX2421/MAX2422/MAX2460/MAX2463.

Key Features

  • yield excellent combined downconverter noise figure (4dB) and high linearity with an input third-order intercept point (IP3) of up to +2dBm. The transmitter consists of a variable-gain IF amplifier with more than 35dB control range, an image-reject upconverter with 35dB image rejection, and a poweramplifier (PA) predriver that produces.
