Abstract :
Based on active millimeter-wave monolithic integrated circuits (MMICs), a pair of receiver and transmitter modules have been developed and used for wireless data transmission experiments at 240 GHz with data rates of up to 40 Gbit/s. Both modules are driven with a subharmonic local oscillator, located at 120 GHz and feature broadband quadrature I/Q IF terminals. The receiver module has a maximum conversion gain of 3.8 dB at 240 GHz. The I/Q imbalance stays below 1.9 dB in the frequency range from 200 to 280 GHz. The transmitter achieves a maximum output power of -3.6 dBm.
