Dear Sir,

I want to select the 82 PF SMT capacitor at 2GHz of creating the layout of LNA.When I downloaded the AVX company market available 82 PF SMT capacitor

(1) I have noticed the series resonant frequency (SRF) vs capacitor and ESR vs frequency. I am confused, how I have to select the series ( Example 0402,0805,0603,1210) for my 82 PF at 2GHz and ESR. What is this SRF and ESR graphs, is the significance, while selecting the particular value capacitor. For 82 PF , which series capacitor I need to select. On what basis we have to select the series for particular value capacitor.

(2) How we have to read the capacitor value at particular frequency. Similarly how I have to read the ESR value.

Anybody knows, please can you explain me in detail.
