Abstract :
The use of multi-tone signaling can avoid the high loss of FR4 traces beyond 10 GHz while confining the task of equalization to 2.5-GHz-wide subchannels. This paper presents multi-tone transceiver design issues and derives performance requirements such as linearity, sensitivity, quadrature mismatches, and phase noise. Possible transmitter and receiver implementations are described and a critical interference effect resulting from local oscillator harmonics is identified.
