    The impedance circuit of a magnus s2 chip is ” Input capacitance of 2-3pF parallel to the input resistance of 2284 ohms. I am trying to simulate RFM2100-AER moisture tag in CST Studio Suit but I am not sure which capacitance value in between 2-3pF  should I use? Any suggestion would be very helpful. Thanks

    Hi…

    I have never found measurements on the X2 series 2 impedance I have just taken them – it seems to be an easy load, minimum impedance is around 3.5 ohms and a low phase angle, always between -20 and 35 degrees. Next time I listen to the Q7 I will try to take some measurements of its impedance. I attach the Alexandria X2 series 2 graphs – the spikes in the graphs are just noise.
