The exploratory development is described of a slow-wave UHF ferrite phase shifter. The real and imaginary parts of the initial permeability are given for a large percentage of the commercially...
MICROWAVE ACOUSTIC DELAY LINE AND RELATED ACTIVE DEVICES. (2005)
Sakiotis,N. G., Brendecke,W., Hickernell,F., Medina,M.
Theoretical and experimental investigations of electroacoustic interactions were conducted as a basis for development of active and passive acoustic devices. To demonstrate these phenomena,...
INVESTIGATION OF NEW MICROWAVE DELAY TECHNIQUES (1998)
Iden ifiers: Birefringent delay lines. The ferrite birefringent-mode delay techniques resulted in the most compact and most lossy delay lines to date at X-band frequencies. The main obstacles are the...
ACTIVE ACOUSTIC DEVICES. (1998)
Sakiotis,N. G., Brendecke,W. H., Hickernell,F. S.
Investigations of suitable heat sink material needed for CW operation resulted in the development of a BeOloaded epoxy with a thermal conductivity of 1.6 BTU/HrFt-degrees F. This appears compatible...
ACTIVE ACOUSTIC DEVICES. (1998)
Sakiotis,N. G., Brendecke,W. H., Hickernell,F. S.
A heat sink design has been demonstrated which maintains the maximum crystal temperature rise to less than 10 C above ambient for a range of values of drift field power density required for useful...
ACTIVE ACOUSTIC DEVICES. (1998)
Sakiotis,N. G., Brendecke,W. H., Hickernell,F. S.
Thin film transducer techniques have yielded conversion losses of 6 to 8 db with bandwidths of the order of 50% in the frequency range of 100 to 300 megacycles. Surface roughness and pinholes have...
