Triple/Dual-Mode

CDMA LNA/Mixers

________________General Description

____________________________Features

ꢀ 2.7V Operation

The MAX2323/MAX2325 are low-noise amplifier (LNA)

plus mixer ICs optimized for code-division multiple-access

(CDMA) applications in both cellular and PCS bands. The

MAX2323 addresses dual-band, triple-mode CDMA appli-

cations by providing switched signal paths for cellular FM,

cellular CDMA, and PCS CDMA. The MAX2325 is a cellu-

lar-band dual-mode version.

ꢀ Dual Band, Triple Mode

ꢀ Three LNA Gain Settings (Cellular)

ꢀ Two LNA Gain Settings (PCS)

ꢀ 18mA in Low-Gain Mode

19.5mA in Paging and Midgain Mode

26.5mA in High-Gain, High-Linearity Mode

To optimize cellular-band dynamic range at minimum cur-

rent, the MAX2323/MAX2325 implement four LNA states:

high gain/high linearity, high gain/low linearity, midgain,

and low gain. In high-gain/high-linearity mode, the

adjustable high-intercept LNA minimizes desensitization in

the presence of a large interfering signal. For the other

gain states, the LNA current is reduced to improve stand-

by time.

16.5mA in FM Mode, High-Gain, Low-Linearity

Mode

ꢀ 2.5dB (typ) Cascade Noise Figure

ꢀ Adjustable LNA IIP3, +5dBm to +13dBm

ꢀ Ultra-Small 28-Pin Package (5mm x 5mm)

The CDMA mixers are designed for high linearity, low

noise, and differential IF outputs, while the FM mixer is

designed for lower current and single-ended output. Each

band is implemented with a separate mixer to optimize

performance for the specific band.
