2.7V, Single-Supply, Cellular-Band

Linear Power Amplifiers

General Description

Features

ꢀ Low Average CDMA Current Consumption in

The MAX2264/MAX2265/MAX2266 power amplifiers are

designed for operation in IS-98-based CDMA, IS-136-

based TDMA, and PDC cellular telephones operating in

the 900MHz range. When matched for CDMA operation

and biased with margin over the adjacent and alternate

channel specification (-45dBc/-56dBc), the amplifiers

achieve 28dBm output power with 37% efficiency

(MAX2265). At +16dBm output—a very common power

level for CDMA phones—the MAX2265 still has 7% effi-

ciency, yielding excellent overall talk time. At the same

power level, the MAX2264/MAX2266 have an unprece-

dented 12%/17% efficiency, while still obtaining

32%/32% efficiency at maximum output power.

Circuitry Needed

ꢀ Supply Current and ACPR Margin

The MAX2264/MAX2265/MAX2266 have internally refer-

enced bias ports that are normally terminated with sim-

ple resistors. The bias ports allow customization of

ACPR margin and gain. They can also be used to

“throttle back” bias current when generating low power

levels. The MAX2264/MAX2265/MAX2266 have excel-

lent gain stability over temperature ( 0.8dB), so

overdesign of driver stages and excess driver current

are dramatically reduced, further increasing the

phone’s talk time. The devices can be operated from

+2.7V to +5V while meeting all ACPR specifications

over the entire temperature range. Nonlinear efficiency

is 48% when matched for linear operation, or 55% when

matched for non-linear-only operation (MAX2265).
