TRF1223 is a power amplifier chip from Texas Instruments. It works in the frequency range of 3.3-3.8GHz and has an output power of 1W. It has 16dB of gain steps and 1-bit TTL control signals, which can achieve a total gain control of 32dB.
The TRF1223 is a highly integrated linear transmitter/power amplifier (PA) MMIC designed for complex modulation schemes such as high-order QAM or OFDM. It features two 1-bit, 16-dB gain steps providing a total of 32 dB of gain control via TTL signals and includes an auto-bias design with PA enable functionality.
The device integrates a temperature-compensated directional coupler detector for output power monitoring or automatic level control (ALC) applications. Key specifications include a peak output power of +30 dBm, a third-order intercept point (+45 dBm IP3), and operation over the 3300 MHz to 3800 MHz frequency range.
