ARVIZU, A.; REYNOSO-HERNANDEZ, J.A.; CHAVEZ, M.A.  e  SANCHEZ, J. de D.. Foto-transceptor para sistemas RoF y RoFSO usando un mezclador optoelectrónico basado en PHEMT. Rev. mex. fis. [online]. 2012, vol.58, n.4, pp.339-347. ISSN 0035-001X.

This paper deals with the application of self-oscillating optoelectronic mixers based on the use of a pseudomorphic high electron mobility transistor (PHEMT's) in radio over optical fiber (RoF) and radio over free space optics (RoFSO) systems. We describe the development of photoreception stages (down conversion) and up-conversion stages for such systems for two different wavelengths: 1550 nm using a mixer based on a PHEMT on InP substrate as active device for detection and another one with a PHEMT on GaAs substrate at 850 nm. We report the characterization results both for not illumination and illumination conditions. We also describe the results obtained on a typical application of GSM over optical fibers.
