Multi-Gigabit Wireless data transfer at 60 GHz

摘要

In this paper we describe the status of the first prototype of the 60 GHzwireless Multi-gigabit data transfer topology currently under development atUniversity of Heidelberg using IBM 130 nm SiGe HBT BiCMOS technology. The 60GHz band is very suitable for high data rate and short distance applications asfor example needed in the HEP experments. The wireless transceiver consist of atransmitter and a receiver. The transmitter includes an On-Off Keying (OOK)modulator, an Local Oscillator (LO), a Power Amplifier (PA) and a BandPassFilter (BPF). The receiver part is composed of a BandPass- Filter (BPF), a LowNoise Amplifier (LNA), a double balanced down-convert Gilbert mixer, a LocalOscillator (LO), then a BPF to remove the mixer introduced noise, anIntermediate Amplifier (IF), an On-Off Keying demodulator and a limitingamplifier. The first prototype would be able to handle a data-rate of about 3.5Gbps over a link distance of 1 m. The first simulations of the LNA show that aNoise Figure (NF) of 5 dB, a power gain of 21 dB at 60 GHz with a 3 dBbandwidth of more than 20 GHz with a power consumption 11 mW are achieved.Simulations of the PA show an output referred compression point P1dB of 19.7 dBat 60 GHz.
