Part Number: TRF7962A

Hi team,

Please see the  TRF7962A datasheet  Figure 7-2. Impedance Matching Circuit.

C4,C5, C7 and C8, C9, C10, C11 are sensitive for different cap brand?

Thank you!

    Hello Zoe,

    The cap brand/manufacturer isn't important but tolerance can be. Worst tolerance used should be 10%, but we recommend 5% is generally good enough but if a system is intended to be maximum performance than 1% is even better for that. Some of our EVM's use some 10% components though and the performance is still fine with that, but we wouldn't approve on our end of the use of anything higher than that.
