TRF2443 用于宽带无线应用的集成 IF 收发器

TRF2443 is a highly integrated full-duplex intermediate frequency (IF) transceiver designed for broadband point-to-point wireless communications applications. The receiver chain integrates a quadrature (IQ) demodulator and provides more than 90 dB of gain range, obtained via a combination of analog and digital controlled VGAs. The integrated programmable baseband low-pass filter gives the TRF2443 the flexibility to receive signals with different bandwidths, while also helping to remove interferer signals before they reach the ADC. Additionally, the TRF2443 gives the flexibility to add an external IF filter to further remove unwanted signals. The TRF2443 transmitter chain integrates a quadrature (IQ) modulator driving a highly linear IF DVGA that provides 35 dB of gain range controlled via a serial programming interface (SPI).
