Direct Downconversion Receiver

Check for Samples: TRF371109

FEATURES

DESCRIPTION

The TRF371109 is a highly linear direct-conversion

quadrature receiver. The TRF371109 integrates

balanced I and Q mixers, LO buffers, and phase

splitters to convert an RF signal directly to I and Q

baseband. The on-chip programmable gain amplifiers

allow adjustment of the output signal level without the

need for external variable gain (attenuator) devices.

The TRF371109 integrates programmable baseband

low-pass filters that attenuate nearby interference,

eliminating the need for an external baseband filter.
