General Description
The MAX2424/MAX2426 highly integrated front-end ICs provide the lowest cost solution for cordless and ISM-band radios operating in the 900MHz band. Both devices incorporate a receive image-reject mixer (to reduce filter cost) as well as a versatile transmit mixer. The devices operate from a +2.7V to +4.8V single power supply, allowing direct connection to a 3-cell battery stack.
