MAX2426 Datasheet | Maxim Integrated

Description The MAX2424/MAX2426 highly integrated front-end ICs provide the lowest cost solution for cordless and ISMband 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. 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 third-order intercept point (IIP3) of up to +2d Bm. The transmitter consists of a double-balanced mixer and a power amplifier (PA) predriver that produces up to 0d Bm (in some applications serving as the final power stage). It can be used in a...
