The TRF1216 is the first of two integrated circuits used in the receiver section of Texas Instruments ' 3.5-GHz radio chipset. The TRF1216 down-converts the 3.5-GHz input frequency to an intermediate fre- quency in the range of 400 MHz to 500 MHz. The device provides a differential output that passes through a SAW filter before connecting to a second down converter. For the best performance, Texas Instruments TRF1212 should be used to perform both the second down conversion and also provide the Local Oscillator for the TRF1216.
The TRF1216 includes a LNA with switchable attenu- ation, a balanced mixer, a variable gain IF amplifier and a differential LO Buffer for improved perform- ance. In order to provide exceptional image rejection and extra jammer immunity, the TRF1216 offers a signal path to an off-chip filter. Specifications are provided assuming an in-band 2-dB insertion loss filter. To maximize input dynamic range, a 10-dB switchable attenuator is provided in the RF path as well as 10dB of analog IF gain control. After the image reject filter, an on-chip balun converts the signal from single ended to differential in order to provide better noise immunity at the mixer.
