A quantity closely related to directive gain is power gain, gp. For an ideal antenna with a radiation efficiency of 100%, directive gain is equal to power gain. For an antenna with losses (excluding reflection losses arising from impedance mismatch), power gain will be lower than directive gain, and is given by the equation: G p = g d η

The signal power received is too low signal must be amplified first (gain). The term gain usually refers to amplification. For an amplifier, the gain (A) is the ratio of the output to the input. So, to calculate power gain (A P) where P in is the power input and P out is the power output: =𝑷 /𝑷𝒊 (unitless)

Oct 10, 2013 · Friis Equation Origins Derived in 1945 by Bell Labs worker Harald T. Friss Gives the amount of power an antenna received under ideal conditions from another antenna – Antennas must be in far field – Antennas are in unobstructed free space – Bandwidth is narrow enough that a single wavelength can be assumed – Antennas are correctly aligned and polarized

Basic Calculation of an Inverting Buck-Boost Power Stage IlonaWeiss ABSTRACT This application note provides basic formulas that you need to design the power stage of an inverting buck-boost converter. The premise is that the power switch is integrated in the IC and the rectification is done by a diode (non-synchronous power stage).
