Infineon Technologies has begun the production of its BGTx0 chipsets for wireless backhaul communication systems. The company stated that the transceiver family offer a complete RF front-end for wireless communication in 57-64GHz, 71-76GHz or 81-86GHz millimeter wave bands. Paired with a base band/modem, the system solution requires less space, offers improved reliability and lower cost for the critical wireless backhaul links needed in mobile base stations that support LTE/4G networks, the firm added.

The lead customer Sub10 Systems is qualifying BGT70 and BGT80 E-band transceivers for an frequency division duplex (FDD) system. Mark Stevens, CTO at Sub10 Systems, said: "We are delighted to be collaborating with Infineon on integration of the BGT70 and BGT80 chipset into our newly developed E-band transceiver. We expect high performance and high reliability at the same time, therefore we have chosen the best solution in the market." The targeted system supports a data rate of more than 1Gb/s with link distances of about 2.5km.

Infineon's BGTx0 family claims to simplify system design and production logistics by replacing more than 10 discrete devices by a single device. Due to their low power consumption, the single-chip high-integration transceivers also help to reduce operating expenses in high data rate millimeter wave infrastructures, Infineon continued.

Each mobile communication standard uses specific frequency bands to transport data. Current standards operate below 43GHz, known as microwaves. As future standards, such as the latest LTE/4G, will require more capacity and higher data rates, public authorities have released V- and E-band using millimeter waves. Network operators are expected to invest heavily in small cell infrastructures in the years ahead in order to provide mobile phone users with high speed internet and full network coverage.

Engineering samples of BGTx0 transceivers are available. Volume production is planned for spring 2014.
