TRF371125数据手册RF/IF射频/中频RFID的RF解调器规格书PDF

描述 Description

The TRF371125 is a highly linear and integrated direct-conversion quadrature demodulator. The TRF371125 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 TRF371125 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 QFN package, the TRF371125 provides the smallest and most integrated receiver solution available for high-performance equipment.
