IQ解调器 IQ DEMODULATOR
DESCRIPON
The TRF3710 is a highly linear and integrated direct-conversion quadrature demodulator optimized for third-generation 3G wireless infrastructure. The TRF3710 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 TRF3710 integrates programmable baseband low-pass filters that attenuate nearby interference, eliminating the need for an external baseband filter.
