Dual RF Power Amplifier Linearizer (RFPAL)

Fourth Generation Fully Adaptive RF PA Linearization Technology in a Single IC

Product Details

The SC2200 belongs to the 4th-generation family of RF PA linearizers (RFPAL) that provides increased integration and functionality over the previous generations. The device is a dual-path linearizer that is a fully-adaptive, RFIN/RFOUT predistortion linearization solution optimized for a wide range of amplifiers, power levels, and communication protocols. It supports 2G to 4G standards (FDD and TDD) from 698MHz to 2700MHz as well as an expanded range of signal bandwidths from 60MHz down to 1.2MHz. The SC2200 accepts single-ended RF signals to eliminate baluns and features a mirrored pinout facilitating design of both paths. The device uses the PA output and input signals to adaptively generate an optimized correction function to minimize the PA’s distortion. Using RF-domain analog signal processing enables the SC2200 to operate over wide bandwidths and with very low power consumption. The dual linearizer is optimized for high-performance MIMO applications, including small cells, active antenna, and distributed antenna systems.

Description

The SC2200 evaluation kits (SC2200-EVK) provide the hardware and software graphical user interface (GUI) necessary for the evaluation of the SC2200. The SC2200 belongs to the 4th-generation family of RF PA linearizers (RFPAL) that provide increased integration and functionality over the previous generations. The SC2200 is a dual-path linearizer that is a fully-adaptive, RFIN/RFOUT predistortion linearization solution optimized for a wide range of amplifiers, power levels, and communication protocols. It supports 2G to 4G standards (FDD and TDD) from 698MHz to 2700MHz, as well as an expanded range of signal bandwidths from 60MHz down to 1.2MHz. The device accepts single-ended RF signals to eliminate baluns and features a mirrored pinout facilitating design of both paths. The SC2200 uses the PA output and input signals to adaptively generate an optimized correction function to minimize the PA’s distortion. Using RF-domain analog signal processing enables the SC2200 to operate over wide bandwidths and with very low power consumption. The dual linearizer can be used for small cell MIMO, active antennas, distributed antennas, or in systems requiring two different simplex bands.

Description

SC-USB-SPI2# is an adapter used for converting a computer’s USB interface connection to the serial parallel interface (SPI) used by the SC2200. This is not required for operating the SC2200 evaluation kits. It is only recommended for prototypes debug and/or programming linearizer during manufacturing (if no other means available such as onboard micro controller).

Only two connections are required for use with the SC2200 and no external power supply is required. The USB connection from the host computer is made through a standard USB 2.0 cable – a male-to-micro-USB B connected to female connector, J20, on SC-USB-SPI2#. The interface connection between the board containing the SC2200 and the SC-USB-SPI2# adapter is through J1.

This adapter can only be used to run one instance of the SC2200 GUI at a time. Conflicts will occur when running multiple SC2200 GUIs trying to open the same SPI communication pipe.

Typical Operating Temperature: +25°C
