Design for a Current Transformer RF
Sampler
Io = sqrt(Tx power / 50)
Is = Io/N
I1 = Is * (Rser + Rsa)/sum(Rj)
I2 = Is*Rsh/sum(Rj)

Transmitter Monitoring
Rsh = 100 * N * sqrt (Psa/Po)
N = Rsh * sqrt (Po/Psa)/100
dB = 10 * log (Psa/Po)
Simplification: To
maintain impedance
balance and reduce
required N for a given dB
Rsh
+ Rser
Rload
=
Rsa = 50
= 50
