Data Sheet
Normalized transfer function (passband, measured balanced-balanced)
Test matching network to 1000 Ω (element values depend on pcb layout)
Rs1 = 470 Ω
LP1 = 220 nH
The insertion attenuation of the above mentioned network includes 26,8 dB additional loss due
to the impedance transformation to 1000Ω and the losses of the two baluns.
