Dear Sirs,
I want to connect a single, multiband antenna to the WIFI & LTE Main connection. To achieve this I was thinking about using a Combiner/Divider (e.g. the InStock PD2020). This is a basically a power-splitter/combiner covering the desired frequencies. It has a channel isolation of 22dB. Since the WIFI and LTE frequency in use are very close, the use of filters with their crossover between WIFI and LTE is not possible. But with the combiner, a small RF signal will 'leak' back into the LTE input/output when transmitting on WIFI (and the other way around). Now this will be 22 dB attenuated with respect to the WIFI or LTE output signal.
Can you tell me if the WIFI and LTE input/output are immune to these 'out of band' signal levels ?
I'm looking forward to your response :-)
Kindest regards from The Netherlands
Peter
