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.
