TA0030 - TRANSMIT AND RECEIVE AGC AMPLIFIERS FOR CDMA CELLULAR /PCS PHONES

Key Features

  • a 90dB gain range from -48dB power gain to +42dB power gain and is powered from a single 3.6V supply. In a cellular system, the cellular base station sends control signals to the mobile phone Copyright 1997-2000 RF Micro Devices, Inc. TA0030 Figure 2) while keeping down the noise figure of the device (see Figure 3). Although the noise requirements for the transmit AGC amplifier are not as stringent as that of the receive AGC amplifier, the challenging IIP3 requirements for the RF2609 make the.

TA0030  TA0030 RF2607, RF2609: Transmit and Receive AGC Amplifiers for CDMA Cellular/PCS Phones               Cellular and Personal Communication Services (PCS) phones that are based on Code Division Multiple Access (CDMA) need careful regulation of signal levels on both the forward and reverse channels. In the reverse channel (mobile phone to base station) a transmit automatic gain control (AGC) amplifier must carefully adjust the output power of the mobile so that it does not dominate the input spectrum at the base station. Each mobile's signal should arrive at the base station at the same power level; this helps ensure that capacity is maximized.
