A fully integrated transmitter (TX) front-end for wireless communication at 60 GHz, produced in 0.25 μm SiGe:C BiCMOS technology is presented. The transmitter features a modified heterodyne topology with a sliding intermediate frequency (IF). The TX features IF I/Q mixers, an IF amplifier, a 60 GHz mixer, a phase-locked loop, an image-rejection filter and a power amplifier. The measured...
60 GHz millimeter wave technology has become an attractive solution for wireless communication in the most recent market. In the draft of IEEE 802.11ad standard, two modulation schemes are being considered in the design of physical (PHY) layer, namely, Single-Carrier (SC), and Orthogonal Frequency Division Multiplexing (OFDM). In this paper, the error performances of both coded modulation schemes...
This paper presents a detailed analysis of the impact of power amplifier (PA) non-linearity on the performance of single carrier (SC) and OFDM systems in 60 GHz spectrum. The efficiency of the considered systems was analyzed by estimating values of the power amplifier output backoff needed to meet the requirements on the transmit spectrum mask (TSM) compliance and error vector magnitude (EVM). Different...
This paper presents a fully integrated transmitter front-end for 60 GHz wireless communication, produced in 0.25 mum SiGe:C BiCMOS technology. The transmitter features a mixer, a phase-locked loop (PLL), a preamplifier, an image-rejection filter and a power amplifier (PA). The measured single-ended 1dB compression point at the output is 10.5 dBm and the saturated power is 14.9 dBm. Error free data...
