TRF1222 Overview
The TRF1222 up-converts a UHF IF signal to an RF signal in the 3300 to 3800 MHz range for 3.5-GHz radio applications. The TRF1222 has 18 dB of gain and an output P-1dB of 14 dBm, typical. A TTL patible, 1-bit 16-dB digital attenuator is provided for gain control and the IF and RF amplifiers can be shut off via a TTL control signal for power critical or TDD applications.
