Analog Devices has collaborated with Altera on a development platform for applying its DPD (digital pre-distortion) techniques in multi-carrier mobile basestations.
ADI's MS-DPD (mixed-signal, digital pre-distortion) development platform can now be integrated with FPGAs for the two leading suppliers.
It is already compatible with Xilinx FPGAs for the design of multi-carrier GSM and multi-standard SDR (software-defined radio) basestations with the creation of FPGA-based digital pre-distortion (DPD) algorithms.
According to Martin Cotter, segment director, Communications Infrastructure, Analog Devices: "By collaborating with Altera, ADI is now able to offer customers the complete circuitry and components needed to implement a basestation radio."
FPGAs are being used in multi-carrier GSM and multi-standard SDR (software-defined radio) applications for re-programming DPD algorithms during product development to correct for non-linearities in the radio's transmit paths and improving power efficiency.
"The MS-DPD board has native support for Altera's HSMC connector and can seamlessly interface with the FPGA development kits from Altera and our partners,” said Arun Iyengar, senior director of Altera's communications business unit.
ADI's MS-DPD development board includes more than 12 RF and mixed-signal components, including the recently announced AD9122 1.2-GSPS digital-to-analogue converter and ADL5375 quadrature modulator.
There are also the usual amplifiers, mixers, clock ICs, power management ICs, and PLL (phase-locked-loop) circuits.
