Data Sheet
Test matching network to 50Ω, balanced low pass matching circuit (actual element values depend on PCB layout. Serial inductance values by combination of 39nH / 47nH. S-parameters of
transformers TOKO B5FL available on request):
Cp1 = Cp4 = 6,8 pF
Ls2 = Ls3 = 43 nH
Test matching network to 50Ω, single-ended or pseudo-balanced (serial inductances splitted up
into both signal paths, improved ultimate rejection) low pass matching circuit (actual element values depend on PCB layout):
Cp1 = Cp4 = 5,6 pF
Ls2 = Ls3 =2 x 39 nH
