The data-rate of 120Gb/s is realized by two 15GBaud data streams in 16-QAM modulation (2×15×4b/symbol=120Gb/s). The total 30GBaud signal is up- and down-converted with 70GHz and 105GHz LO signals, which are generated by a doubler and a tripler from an external 35GHz source input with more than 29dBc and 38dBc undesired harmonic suppression, respectively. Single-IF balanced mixers are employed in the TX with an LO leakage-cancellation technique. Hence, the TRX is capable of transmitting and receiving the whole bandwidth of 35GHz. The power
