Design of Inherently Wide-Band Microwave Frequency Doubler and Tripler in Microstrip (Ontwerp van Inherent Breedbandige Microgolf Frequentie- Verdubbelaar en Verdrievoudiger in Microstrip)
Abstract
Two modern wide-band and frequency agile radar systems, currently under construction at TNO-FEL, require the development of a wide-band S-band frequency doubler and a wide-band X-band frequency tripler. The wide-band requirement, however, is hard to meet when using the classical approach. Wave- form invariance as an alternative concept to achieve inherently wide-band behaviour is proposed. From this, a new design goal is derived and formulated: constant admittance at the terminals of the non-linear device within each harmonic sub-band. A frequency doubler has been designed and built based on this concept; the conversion efficiency measure (1.0 + or - 0.7) dB in the 2.8 ... 3. 6 GHz design band. Also, a frequency tripler has been designed and built based on this concept; the conversion efficiency measures (-10.4 + or - 0.6) dB in the 8.5 ... 10.5 GHz design band. Both examples prove the validity and practical suitability of this alternative concept. Netherlands.
