how do i design the bypass capacitor on the dc biasing line for an amplifier.
how to i decide the value i should used to attenuate high frequency noise from dc line going in the the frequency of interest, for example gps 1575, cell low band of 800Mhz, cell high band of 2100Mhz.
should i choose the capacitor with low or close to 0 reactance value so that i will provide a low impedance path for the noise to go back to ground?
