TRF8011 900-MHz RF TRANSMIT DRIVER

The TRF8011 RF transmit driver amplifier is for use in 800 to 1000 MHz wireless communication systems. It consists of a two-stage amplifier and a linear ramp controller for burst control in TDMA (time-division multiple access) applications. Very few external components are required for operation. The input is dc-blocked and requires no external matching. The.

Features

Very few external components are required for operation. The input is dc-blocked and requires no external matching. The output requires external matching suitable for the application frequency. The device is enabled when the TXEN input is held high. A power control signal applied to the VPC input can ramp the RF output power up or down to meet ramp and spurious emission specifications in TDMA systems. The power control signal causes a linear 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 and TXEN high, adjusting.
