digitalTRX - Lower Effort, Power and Cost.
With a portfolio of advanced linear, non-linear and adaptive signal processing blocks digitalTRX provides a flexible approach to Remote Radio Unit and Software Defined Radio development.
A fully configurable processor supplied on an industry leading low power programable logic process, digitalTRX supports integration of all digital transciever functionality including crest factor reduction and digital predistortion into a single silcon device with leading power, cost and performance.
Digital Pre-distortion
Digital Pre-distortion has become the industry standard for linearity improvement in digital transmitter designs. By applying an inverse non linearity to the modulator output, digital pre-distortion dramatically improving amplifier linearity, efficiency and cost.
Affarii's highly integrated Digital Pre-distortion solution supports linearisation of 20MHz of signal bandwidth with up to 30dB ACLR correction capability when operated with Doherty and Class-AB amplifiers, while consuming only 1/2 W of baseband power.
