Hello,
Now, we are testing the leakage power (EMC test) of TRF7962A (on our custom board) in the 200mW output mode.
Because of the test, the leakage power level (200MHz - 800MHz) is higher than the level defined by regulation due to harmonic.
Could you confirm the following questions?
1.Do you know the way to remove the harmonic (200MHz - 800MHz)?
2.We are considering inserting capacitors to pin 5 (TX_OUT) and implementing LPF to remove the harmonic.
Could you advise us how large capacitor can connect to pin 5?
Also, is there any important point to connect the capacitor?
Of course, we are referring the reference design and copying the constant value.
The output wave from TRF7962A is following.
We can see the harmonic from 200MHz to 800MHz.
Best Regards,
Nomo
