Frequency Range: 1700 MHz to 6000 MHz  
The TRF371135 is a highly linear and integrated  
direct-conversion quadrature demodulator. The  
TRF371135 integrates balanced I and Q mixers, LO  
buffers, and phase splitters to convert an RF signal

baseband. The on-chip  
programmable-gain amplifiers allow adjustment of the  
output signal level without the need for external  
variable-gain (attenuator) devices. The TRF371135  
integrates programmable baseband low-pass filters  
that attenuate nearby interference, eliminating the  
need for an external baseband filter.  
Single Supply: 4.5-V to 5.5-V Operation
