The RF2138 is a high power, high efficiency power amplifier module offering high performance in GSM or GPRS applications. RF2138 is manufactured on an advanced GaAs HBT process, and has been designed for use as the final RF amplifier in GSM hand held-digital cellular equipment and other applications in the 800MHz to 950MHz band. On-board power control provides over 70dB of control range with an analog voltage input, and provides power down with a logic "low" for standby operation. RF2138 is self-contained with 50Ω input and the  output can be easily matched to obtain optimum power and efficiency characteristics. The RF2138 can be used together with the RF2140 for dual-band operation. RF2138 is packaged in an ultra-small ceramic package, minimizing the required board space.
