Overview

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.
In the forward channel (base station to mobile) a receive AGC amplifier adjusts to accommodate widely varying signal levels coming in from the base station.
At a CDMA mobile phone antenna numerous signals sent from the cell base station are layered on a single frequency ban...
