Hi
how do i choose the decoupling capacitor for DC bias line to a IC.
i think 0.1uF and 10uF are common one.
But what if i have a cellular switch IC which operating in different cellular band lets say 800MHz and 2100MHz.
how do i choose the value of the decoupling capacitor for the dc bias line for the cellular switch IC so that i wanted to attenuated or bypass any high frequency noise , 800MHz and 2100 Mhz in the dc line.
