TRF371109IRGZT

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.Housed in a 7-mm × 7-mm VQFN package, the TRF371109 provides the smallest and most integrated receiver solution available for high-performance equipment.
