The 6 dB Power Splitter/Combiner is built in an Original size FLEXI-BOX on a dedicated PCB. The connectors can be selected from BNC, N, SMA and TNC. The box has one 50Ω input and two 50Ω outputs. It is intended as a measurement aid and is also part of the "Standing Wave Kit". We can build and test these at Chemandy with an insertion loss of 6.0 dB ± 0.2 dB at 0.3 MHz to 7.0 dB ± 0.5 dB at 3 GHz when using SMA connectors.     


    The 6 dB splitter uses standard 0805 1% resistors. The value required is 16.667 Ω, which is not a preferred value in the E12 series. This is overcome by using two 33Ω in parallel (16.5Ω). The use of two resistors in parallel also reduces the effect of the series inductance of the resistors and gives an improved insertion loss at high frequencies. This can be observed in the figure below.
