The MAX2232/MAX2233 low-voltage, silicon RF power
amplifiers (PAs) are designed for use in the 900MHz
ISM band. They operate from a single +2.7V to +5.5V
supply, allowing them to be powered directly from a 3-
cell NiCd or a 1-cell Lithium-Ion battery. The devices
typically deliver 250mW (+24dBm) of output power at
915MHz from a single +3.6V supply, or 150mW
(+22dBm) from a single +2.7V supply. At +24dBm out-
put power, power-added efficiency (PAE) is 44%.
The MAX2232/MAX2233 provide 24dB of gain, which is
adjustable over a continuous 24dB span via the analog
gain-control pin of the MAX2232 or in two 10dB steps
via the 2-bit programmable gain-control DAC of the
MAX2233. An external capacitor sets the RF output
power envelope ramp time, reducing spurious emis-
sions during power-up and power-down by providing a
gradual change in output power (MAX2232).
The MAX2232/MAX2233 feature a low-power shutdown
mode, which typically draws less than 1µA of supply
current, saving power during “idle slots” in time-division
multiple-access (TDMA) systems. The ∆VSWR of the RF
input in shutdown mode relative to normal operation is
1.2:1. The devices also feature a thermal shutdown
function, enabling the PA to protect itself from excessive
temperature conditions that could damage the IC. A
capacitor to ground limits thermal cycling by setting a
thermal shutdown timeout period.
The MAX2232/MAX2233 are available in a space-sav-
ing, thermally enhanced 16-pin power-QSOP (PQSOP)
package.
