Abstract
IQ wireless GmbH developed a family of modular SDR transceivers to serve a wide range of different mission scenarios. Transceivers of this family are formed by two printed circuit boards accommodated in a compact housing. The SDR platform handles data interface and coding, while the analogue frontend implements frequency conversion and amplification. To increase the potential for customization, the architecture provides two independent channels for both up- and downlink. The first implementation of the new transceiver design is the X band transmitter XLink that was developed in cooperation with Technische Universität Berlin. Here, the two downlink channels are both configured for X band transmission. In a first development step, broadband data rates up to 25 Mbps are achieved and CCSDS compliance facilitates the use of existing ground infrastructure. Alternative configurations use both channels for redundancy and MIMO to implement highly reliable and efficient proprietary transmission modes. The implementation of increased data rates in the range of 150 Mbps is currently investigated. The two uplink channels of XLink are configured to support X and S band, respectively. This paper presents the transceiver family’s architecture and details the XLink configuration including results from the ground qualification campaign and performance testing.
