Mm-wave Wideband Mimo Channel Sounding
The use of wideband 60 GHz radio propagation channel will allow high data rates in future communication systems [1]. E.g., the 57...64 GHz frequency band will allow Gbit data rates for short-range wireless access. Indeed this frequency range offers huge bandwidths and, due to the oxygen absorption, improves frequency reuse in cellular networks compared to lower frequencies. Furthermore, array s...
متن کاملFully Differential mm/sub-mm Wave CMOS Amplifiers
This paper presents an effective design methodology and flow, which is validated through three mmwave/sub-mm-wave amplifiers: including W-band LNA with NF=7dB, W-band PA with PAE >11% and D-band amplifier with gain>20dB. The CMOS based amplifiers can be integrated with III-V materials to form heterogeneous integration, such as COSMOS, to achieve the best performance for various applications.
متن کاملCompact Slow-Wave Branch-Line Coupler Using Crossing Bond Wires
This paper proposes a compact and miniaturized branch-line coupler using a crossing bond wire structured slow-wave branch line (CBWSWB). The proposed coupler achieves a size reduction of 82% compared with a conventional implementation. Measured S11, S21, S31 and S41 of the proposed coupler are better than −24, −3.7, −3.7 and −28 dB at 3GHz, respectively. Furthermore, the phase difference betwee...

متن کاملSensitivity Analysis of a Wideband Backward-wave Directional Coupler Using Neural Network and Monte Carlo Method (RESEARCH NOTE)
In this paper sensitivity analysis of a wideband backward-wave directional coupler due to fabrication imperfections is done using Monte Carlo method. For using this method, a random stochastic process with Gaussian distribution by 0 average and 0.1 standard deviation is added to the different geometrical parameters of the coupler and the frequency response of the coupler is estimated. The appli...
