“…For example, use of interpolation filters to meet similar requirements of IEEE 802.15.3c in [2] results in higher power consumption. A low power version of the SC mode reaches data rates of 2.5Gb/s with π/2-QPSK modulation and it finds application in mobile devices where low power transceivers are required [3]. This is the target of our work.…”

IEEE 802.11ad (WiGig) is an emerging multi-Gb/s wireless standard in the unlicensed 60GHz spectrum. This work presents system level validation of a Single Carrier (SC), QPSK modulated WiGig transmitter based on a semi-digital Finite Impulse Response (FIR) Digital-to-Analog Converter (DAC). The 1.76GS/s complex baseband input signal is upsampled by two to a clock frequency of 3.52GHz. In order to introduce channel shaping and meet the standard requirements, the structure implements a 16 th -order direct-form Root-Raised Cosine (RRC) FIR filter. Transmit mask and EVM requirements are met with a large margin while allowing a 14% random mismatches on the current sources implementing the FIR DAC coefficients.
