Infineon introduces SiGe transceiver for mm-wave wireless backhaul systems

Infineon Technologies AG has introduced a Silicon Germanium (SiGe) transceiver for designing high data rate millimeter wave wireless backhaul communication systems. The new transceivers address the market for wireless data links with data rates of more than 1 Gigabit per second (Gbps) between LTE/4G base stations and core networks. The BGTx0 transceivers packs I/Q modulator, Voltage Controlled Oscillator (VCO), Power Amplifier (PA), Low Noise Amplifier (LNA), Programmable Gain Amplifier (PGA), SPI control interface in a plastic eWLB package (embedded Wafer Level Ball Grid Array) chip. Validation and calibration of RF performance occurs in production using Built-In-Self-Test (BIST). The BGTx0 family provides a complete radio frequency (RF) front-end for wireless communication in 57-64 GHz, 71-76 GHz, or 81-86 GHz millimeter wave bands. Paired with a baseband/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, according to Infineon. “The V- and E-band microwave frequencies available for LTE/4G backhaul support data rates three times higher than in earlier generation networks. Correspondingly they need superior RF performance to meet operating requirements,” said Philipp von Schierstaedt, Vice President and General Manager of the Busin...
