A SiGe quadrature transmitter and receiver chipset for emerging high-frequency applications at 160GHz

A158-to-165GHz TX and RX chipset supporting QAM modulation schemes is implemented in SiGe. Double-balanced l/Q mixers are used for direct up-/down-conversion. The LO chain consists of a VCO, a frequency prescaler, a tripler/amplifier chain, and a differential 90deg coupler. The RX further includes a...

More Information
Summary:A158-to-165GHz TX and RX chipset supporting QAM modulation schemes is implemented in SiGe. Double-balanced l/Q mixers are used for direct up-/down-conversion. The LO chain consists of a VCO, a frequency prescaler, a tripler/amplifier chain, and a differential 90deg coupler. The RX further includes an LNA and the TX a PA. The RX system NF is 11 to 14 dB and the TX P sat is up to 5dBm.
