Hello Everyone.

I am planning to use PN7150B0HN and guessing to use an external antenna.

I found one, which is W7001 from www.pulselarsenantennas.com/

and they provide some recommended matching/tunning circuit but I am still having some uncertaincy about it.

Can anyone make recommendations on it?

Here is my schematic:

Thank you

 

 

 

Also 

which should fit my application but I am still have some uncertaincy about matching/tuning circuit.

Hi,

See suggestions below, please!

1. Antenna matching circuit 

It is best to reserve some capacitor positions for this part of the circuit so that they can be used during debugging. For example, you can refer to the DEMO board.

2. Antenna designing tool

---Input your antenna parameters to get values of inductors,capacitors of matching circuits, like below:

Hope above advice is helpful to you.

Have a nice day!
