DC Blocking for A10192H
Hi

I have designed a PCB where I uses the A10192H antenna. I measure the frequency to be around 2800MHz.

I see in the old datasheet for A10192 there is a comment that a DC blocking capacitor is needed between the antenna and the matching circuit. Is that also needed for A10192H?

Your reference designs doesn't include a DC blocking capacitor. Why is that?

What size is recommended to use?

Regards,

Morten

Hi Sir,

A DC block capacitor is not necessary if your design does not have DC power at RF trace.

Since you designed a PCB by using A10192H, it is recommended to refer to A10192H data sheet.
