Texas Instruments has introduced a high-linearity, low-noise intermediate frequency (IF) transceiver with cross-polarization interference cancellation (XPIC) support.
The TRF2443 has an output third order intercept point (OIP3) of 29.5dBm and a receiver noise figure (NF) of 4.3dB.
The linearity and sensitivity of the transceiver make it suitable for wireless infrastructure backhaul and point-to-point microwave end equipment.
There are programmable baseband amplifiers, IF amplifiers, analogue and digital variable gain amplifiers and quadrature modulator and demodulator on chip.
Programmable baseband low-pass filters allow the chip to handle signals with different bandwidths and help to remove unwanted interferer signals.
There is automatic DC offset calibration.
