First of all, suppose the modulating input signal voltage is set to zero. The carrier input is applied to the centre-taps A and B of windings on the two transformers. When the carrier voltage v AB is positive, the diodes D 1 and D 2 are forward-biased and conduct, leaving D 3 and D 4 reverse-biased and effectively open-circuit. The input current from the carrier source enters at point A.It takes into account the attenuation of the transmitted signal due to propagation, as well as the loss or gain due to the antenna. A simple link budget equation looks like this: Received Power (dB) = Transmitted Power (dBm) + Gains (dB) – Losses (dB) Equation 1-3 Link budget. Equation 1-3 Link budget.
