MAX2266
Description
The MAX2264/MAX2265/MAX2266 power amplifiers are designed for operation in IS-98-based CDMA, IS-136based 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 (-45d Bc/-56d Bc), the amplifiers achieve 28d Bm output power with 37% efficiency (MAX2265). At +16d Bm output- a very mon power level for CDMA phones- the MAX2265 still has 7% efficiency, yielding excellent overall talk time. At the same power level, the MAX2264/MAX2266 have an unprecedented 12%/17% efficiency, while still obtaining 32%/32% efficiency at maximum output power.
The MAX2264/MAX2265/MAX2266 have internally referenced bias ports that are normally terminated with simple resistors. The bias ports allow customization of ACPR margin and...
