MAX2232, MAX2233 900MHz ISM-Band, 250mW Power Amplifiers With Analog Or Digital Gain Control

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 output 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 emissions 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 1A 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-saving, thermally enha 883 nced 16-pin power-QSOP (PQSOP) package.
