Product Description
The RF2140 is a high power, high efficiency power ampli-
fier module offering high performance in GSM or GPRS
applications. The device is manufactured on an advanced
GaAs HBT process, and has been designed for use as
the final RF amplifier in DCS1800/1900 hand held-digital
cellular equipment and other applications in the
1700MHz to 2000MHz band. On-board power control
provides over 65dB of control range with an analog volt-
age input, and provides power down with a logic 鈥渓ow鈥?for
standby operation. The device is self-contained with 50鈩?/div>
input and the output can be easily matched to obtain opti-
mum power and efficiency characteristics.The RF2140
can be used together with the RF2138 for dual-band
operation. The device is packaged in an ultra-small
ceramic package, minimizing the required board space.
