High power wide band amplifier using optical techniques and impedance matching to source and load

摘要

An amplifying apparatus has a plurality of series coupled laser diodes that impedance match a signal source impedance and which are optically coupled to at least one PIN diode that impedance matches a load impedance. A high DC voltage is applied to the PIN diode so that gain is obtained and signal power is applied to the load. A plurality of parallel coupled PIN diodes can be used or a series-parallel combination.
