QUESTION

question about antenna
Hello

I bought a product from your company called SR4C033

But I want to know the antenna impedance of SR4C033 for matching

I need to know the antenna impedance to be able to match with LC, but the datasheet you presented does not show the impedance of the antenna, so I ask this question.

Simply put, it is the impedance where the antenna is located (Input Impedance of Antenna)

Hi Park,

We only quote antenna impedance once matched, as it will depend on your transmission line and layout. It is DC open-circuit. You can measure the impedance by breaking the trace between the module and the antenna, connecting a test cable (tails) to the feed (still connected to the antenna), you will need to factor in the electrical delay also in order to 'null-out' the test cable.
We do offer a matching service in our lab, so we can handle the optimisation for you. We provide a full report with matching component values, return loss, efficiency and 2D & 3D radiation patterns. Please contact techsupport@antenova.com to get in touch with your regional representative who will help you with what you need.

Many Thanks

Steve
