The TRF1123 is a highly integrated linear transmitter power amplifier MMIC. The chip has two 16-dB gain steps that provide a total of 32-dB gain control via 1-bit TTL control signals. The TRF1123 also integrates a TTL mute function that turns off the amplifiers for power critical or TDD applications. A temperature compensated detector is included for output power monitor or ALC applications. The TRF1123 has a typical P1dB of 31.5 dBm and a third order intercept of 52 dBm.
The TRF1123 is designed to function as a part of Texas Instruments complete 2.5-GHz chip set. The TRF1123 is used as the output power amplifier or a driver amplifier for higher power applications. The linear nature of the transmitter makes it ideal for complex modulations schemes such as high order QAM or OFDM.
