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" bias current when generating low power levels. The MAX2267/MAX2268/MAX2269 have excellent 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 +4.5V while meeting all ACPR specifications over the entire temperature range.
