Triple arrays are a class of designs introduced by Agrawal in 1966 for two-way elimination of heterogeneity in experiments. In this paper we investigate their existence and their connection to other classes of designs, including balanced incomplete block designs and balanced grids.
An experimental study of a balanced mixer based on 2A116A-1 diodes was carried out.Conversion losses were measured in the input frequency range 2450 ± 45 MHz during downconversion to an intermediate 2125 MHz. Conversion loss does not exceed 20 dB anarrow band 2440±10 The amplitude characteristic taken, from which itcan be seen that it is linear for signals up 0 dBm (1 mW). dependence conversion...
