description  
The TRF7610 is a silicon MOSFET power amplifier IC for 900-MHz applications, tailored specifically for global  
systems for mobile communications (GSM). It uses Texas Instruments RFMOS process and consists of a  
three-stage amplifier with output power control. Few external components are required for operation.  
The TRF7610 amplifies the RF signal from a preceding modulator and the upconverter stages in an RF section  
of a transmitter to a level that is sufficient for connection to the antenna. The RF input port, RFIN, and the RF  
output port, RFOUT, require simple external matching networks.  
A control signal applied to the VPC input can ramp the RF output power up or down to meet ramp and spurious  
emission specifications for time-division multiple-access (TDMA) systems. The power control signal causes a  
change in output power as the voltage applied to VPC varies between 0 V and 3 V. With the RF input power  
applied to RFIN at 5 dBm, adjusting VPC from 0 V to 3 V increases the output power from a typical value of  
43 dBm at VPC = 0 V to a typical value of 35 dBm at VPC = 3 V. Forward isolation with the RF input power  
applied to RFIN at 5 dBm, VPC = 0 V, is typically 48 dB.  
The TRF7610 is available in a thermally enhanced, surface-mount, 24-pin PowerPAD (PWP) thin-shrink  
small-outline package (TSSOP). It is characterized for operation from 40°C to 85°C operating free-air  
temperature. In order to maintain acceptable thermal operating conditions, the device should be operated in  
pulse applications such as the GSM standard 1/8 duty cycle. The package has a solderable pad that improves  
the package thermal performance by bonding the pad to an external thermal plane. The pad also acts as a  
low-inductance electrical path to ground and must be electrically connected to the printed circuit-board (PCB)  
ground plane as a continuation of the regular package terminals that are designated GND.  
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
