About old power splitter from Minicircuits

[joaquin]

Hello:

I am an old Spanish radioham. Recently I got, from surplus, a 4 way power
splitter of Minicircuits.

The model is ZB4PD-4375-1. I asked to Minicircuits about its
characteristics,but they told me that this device was done for a special
customer and this information they can not tell me.

Please, some person from this news knew this code: ZB4PD-4375-1.

Thanks in advance.

Joaquin
