Overview

7V, Single-Supply, Cellular-Band Linear Power Amplifiers MAX2267/MAX2268/MAX2269 General Description The MAX2267/MAX2268/MAX2269 power amplifiers are optimized for IS-98-based CDMA and PDC cellular telephones operating in the Japanese cellular-frequency band.
When matched for CDMA operation, the amplifiers achieve 27dBm output power with 35% efficiency (MAX2268), with margin over the adjacent and alternate channel specification.
At a +17dBm output—a very common power level for CDMA phones—the MAX2268 still has 7% efficiency, yielding excellent overall talk time.
At the same power level, the MAX2267/MAX2269 have an unprecedented 12%/17% efficiency, while still obtaining 28%/29% efficiency at maximum output power.
The MAX2267/MAX2268/MAX2269 have internally referenced bias ports that are normally terminated with simple resistors.
The bias ports allow customization of ACPR margin and gain.
They can also be used to “throttle back” b...
