Full-duplex IF transceiver from TI for wireless backhaul apps

Texas Instruments has introduced the TRF2443, a full-duplex intermediate frequency (IF) transceiver designed for broadband point-to-point wireless communications applications.

The TRF2443 also provides cross-polarization interference cancellation (XPIC) support via an integrated XPIC output amplifier and receiver chain, and it is suitable for building block for implementing the IF transceiver function in the Indoor Unit (IDU), which is connected via coaxial cable interface to the Outdoor Unit (ODU), of a point-to-point microwave backhaul split-architecture system.

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 key features of the TRF2443 are,

Transmit (Tx) OIP3 of 29.5 dBm and receive (Rx) third order input intercept point (IIP3) of 9.5 dBm allows for more complicated modulation schemes and increased data throughput
Programmable baseband low-pass filters provide flexibility to handle signals with different bandwidths and help to remove unwanted interferer signals
Automatic DC offset calibration eases design implementation
Integration of more than 15 functional blocks

"Microwave equipment manufacturers are looking for ways to help reduce the capital and operating expenditures of their service provider customers and the highly-integrated TRF2443 can help to meet that requirement," said David Briggs, general manager of TI's Radio products group.
