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 s ing le + 3.6V s up p ly, or 150mW

(+22dBm) from a single +2.7V supply. At +24dBm out-

put power, power-added efficiency (PAE) is 44%.

♦ 800MHz to 1000MHz Frequency Range

♦ 250mW (+24dBm) Output Power at 915MHz from

+3.6V Supply

♦ +2.7V to +5.5V Single-Supply Operation

♦ 44% Power-Added Efficiency

♦ 24dB Power Gain

♦ 24dB Analog Gain-Control Range (MAX2232)

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).

♦ Three Levels of Digitally Programmed Power Gain

in 10dB Steps (MAX2233)

♦ Programmable RF Power Envelope Ramping

(MAX2232)

♦ Thermal Shutdown

♦ Programmable Thermal Shutdown Timeout Period

♦ 0.2µA Low-Power Shutdown Mode

♦ Low ∆VWSR in Standby and Shutdown Modes

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.
