The pdf article by DWK given below gives a detailed discussion of the various possible diode detector configurations; but as pointed out by Dr Denis Jaisson, the formulae developed from p44 onwards are flawed because they rely on a turn-on angle and a forward voltage that cannot be determined rigorously. Instead, it is necessary to apply a transcendental equation for which the solution involves the W0 branch of the Lambert W function. A rigorous demonstration is given in Denis's paper (available from Researchgate) and leads to a set of closed formulae of sufficient simplicity to be entered directly into a spreadsheet.
Denis's theory supercedes the theory given below, but the general discussion of detector configurations and history might nevertheless be found informative.
