RF2174

0

RoHS Compliant & Pb-Free Product

Typical Applications

鈥?3V DCS1800 (PCN) Cellular Handsets

鈥?3V DCS1900 (PCS) Cellular Handsets

鈥?3V Dual-Band/Triple-Band Handsets

Product Description

The RF2174 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惟

input and the output can be easily matched to obtain opti-

mum power and efficiency characteristics. The RF2174

can be used together with the RF2173 for dual-band

operation. The device is packaged in an ultra-small plas-

tic package, minimizing the required board space.
