Values components matching circuit SR4G008-EVB-1
Hello,

We want to use the SR4G008 GNNS antenna in our desing. I did some testing with the SR4G008-EVB-1 the tuning in the evaluation board is perfect for our usecase. I measured it with a Vector Network Analyser. Can you please let me know what the L and C values are in the matching circuit?

Thanks and best regards,

Hi Richard,

The matching values can be found on page 13 of the datasheet. The shunt component closest to the antenna is a 12nH inductor. The series component is a 1.5pF capacitor. The last shunt is not populated.
