General Description
The MAX2244/MAX2245/MAX2246 single-supply, low-
voltage power amplifiers (PAs) are designed for 20dBm
Bluetooth Class 1 applications in the 2.4GHz to 2.5GHz
band. The MAX2244/MAX2245 deliver a peak output
power of 22dBm with greater than 20dB output-power
control range. The 22dBm output power compensates for
the filter loss between the PA and the antenna, allowing
20dBm to be delivered to the antenna. The MAX2246 pro-
vides a peak output power of 20dBm for a 30% reduction
in supply current.
The PAs integrate a power detector and closed-loop
power-control circuitry to provide nearly constant output
power over the full range of supply voltage, temperature,
and input power level. The voltage at the analog control
input precisely controls the output power level.
The MAX2244/MAX2245/MAX2246 feature a low-current
shutdown mode through a simple logic input. Internal cir-
cuitry automatically controls the ramp-up/down of the
output power level during turn-on and turn-off to meet
Bluetooth spurious emissions requirements.
The devices operate from a 3V to 3.6V single supply.
The MAX2244/MAX2246 have a power-control voltage
range of 0.5V to 2V, and the MAX2245 has a control
voltage range of 0.9V to 2.2V. The devices are pack-
aged in a miniature ultra chip-scale package (UCSP),
significantly reducing the required board area.
