RF Module for QorIQ Qonverge LTE-FDD/TDD and WCDMA (HSPA+) Capable RF Module Designed for QorIQ Qonverge BSC913X SoC-based small cell platforms Overview The RF module for BSC913X-based development platforms, designed by Benetel, can enable all major frequency bands worldwide, including LTE-FDD/TDD and WCDMA (HSPA+) air interfaces. The module features 13 dBm output power at the antenna as well as a low-band Tx/Rx (700 to 1000 MHz) and a high-band Tx/Rx (1700 to 2700 MHz) in a 2x2 MIMO configuration. The design utilizes a 3G/4G transceiver chip and enhanced by our low-noise amplifiers and power amplifiers for maximum stability, accuracy and efficiency. The RF module is designed for small cell applications with a JESD207 and a MaxPHY interface to the BSC913X SoC. As an integral part of our development platform, the module enables home eNodeB development by wireless infrastructure OEMs. The RF module is designed to support 2x2 MIMO operation in addition to dual frequency bands via software selection. These dual frequency bands are configured as high and low bands—the low ranging from 700 to 1000 MHz and the high from 1700 to 2700 MHz, enabling Benetel to supply a wide range of band combinations. The module includes two transmit outputs and two receiver inputs for each frequency band, allowing support for 2x2 LTE and 3GPP WCDMA (HSPA+) transmission and reception.
