The TRF1115 is the first of two ASICs used in the receiver section of Texas Instruments MMDS/MDS/WCS/802.16x chipset. The TRF1115 down-converts the input frequency to an IF frequency in the range of 420 MHz to 480 MHz. The device provides a differential output that passes through a SAW filter before connecting to a second down converter chip. (Note: For the best performance, the Texas Instruments TRF1112 should be used to perform both the second down conversion and provide the local oscillator for the TRF1115.)
In order to provide exceptional image rejection and extra jammer rejection, the TRF1115 offers a signal path to an off-chip filter. Specifications are provided assuming an in-band 1.5-dB loss in this filter. The TRF1115 includes a differential LO buffer, mixer, and IF amplifier for improved performance. After the filter, an on-chip balun converts the signal from single-ended to differential in order to provide better noise immunity in the mixer.
