Osciladores controlados por tension para ‥VHF‥ y banda ‥L‥

This work presents, generic design criteria, and build for two types of voltage controlled oscillators (VCO) operating in the bands “VHF” and “L” for use in communications and radar systems. The design criteria adopted according to the limitations of physical space available (14 mm × 14 mm) because the design demands the use of an encapsulated MINI 16L are pointed. The circuital topologies, as well as constructed and measurements made on the same circuit with the corresponding conclusions are presented.
