ABSTRACT:
A lightwave receiver, suitable for CATV applications, includes an input photodiode that is capacitively coupled to the differential inputs of a balanced amplifier. Biasing of the photodiode may be achieved by connecting the photodiode in series between a pair of resistors, with the differential inputs being taken from either side of the photodiode. This arrangement avoids the use of a transformer, which exhibits considerable high frequency loss, thereby avoiding the bandwidth limitation inherent with a transformer.
