Integrated IF Transceiver For Broadband Wireless Applications

The 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). The TRF2443 includes the two synthesizers for the receiver and transmitter chains, removing the need for external LO generation circuitry and simplifying the implementation of a frequency-division duplexing (FDD) transceiver design. The TRF2443 also provides cross-polarization interference cancellation (XPIC) support via an integrated XPIC output Amplifier and receiver chain. The TRF2443 is an ideal building block for implementing the IF transceiver function in the indoor unit (IDU), which is connected via a coaxial cable Interface to the outdoor unit (ODU), of a point-to-point Microwave backhaul split-architecture system.
