  • A 6-bit, 500-MS/s current-steering DAC in SiGe BiCMOS technology and considerations for SFDR performance 
    Reddy, Reeshen; Sinha, Saurabh (Elsevier, 2015-04)
    This paper presents a six-bit current-steering digital-to-analogue converter (DAC), which optimises the spurious free dynamic range (SFDR) performance of high-speed binary weighted architectures by lowering current switch ...
  • Double resonant stub bandstop filter with pseudo-elliptic response 
    Malherbe, J.A.G., 1940-; Reid, C.A. (Institution of Engineering and Technology, 2010-04)
    A simple wideband bandstop filter that yields equal ripples in both the pass and stop bands, is described. The filter comprises only of two resonant stubs and a connecting transmission line and has a transmission response ...
  • Elliptically shaped quad-ridge horn antennas as feed for a reflector 
    Jacobs, Ockert Botha; Odendaal, J.W. (Johann Wilhelm); Joubert, Johan (Institute of Electrical and Electronics Engineers, 2011)
    Quad-ridge horn antennas of various geometries are considered as possible candidates for a wideband reflector antenna feed. It is demonstrated that shaping the sidewalls of the ridge horns significantly improves the ...
  • A low-cost open-hardware wideband multiple-input–multiple-output (MIMO) wireless channel sounder 
    Maharaj, Bodhaswar Tikanath Jugpershad; Wallace, Jon W.; Jensen, Michael A.; Linde, Louis P. (Institute of Electrical and Electronics Engineers, 2008)
    Due to the complexity of multiple-input–multipleoutput (MIMO) wireless channels, direct measurement is the main viable option for accurate characterization. Details on a new low-cost wideband channel sounder are presented, ...
  • Wideband antenna for 4G MIMO applications 
    Kenny, Caitlin; Odendaal, J.W. (Johann Wilhelm); Joubert, Johan (Wiley, 2017-03)
    A small, wideband, multiple-input-multiple-output antenna is presented for 4G long term evolution (LTE) applications. The proposed antenna consists of a vertically polarized wideband stepped slot, as well as a horizontally ...
  • Wideband bandpass filter with extremely wide upper stopband 
    Malherbe, J.A.G., 1940- (Institute of Electrical and Electronics Engineers, 2018-06)
    The realization of planar wideband bandpass filters with an extremely wide upper stopband is described. The filter design differs from conventional approaches in which it is based on the choice of a wideband bandstop (BS) ...
  • Wideband bandstop filter with sub-harmonic stubs 
    Malherbe, J.A.G., 1940- (Institution of Engineering and Technology, 2011-05)
    The performance of a wideband bandstop transmission line filter employing a series overlay inductor over two stubs resonating at respectively one half and one quarter of the centre frequency, is described. The structure ...
