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. The receive path incorporates an adjustable-gain LNA and an image-reject downconverter with 35d B image suppression. These features yield excellent bined downconverter noise figure (4d B) and high linearity with an input...
