MIC BROADBAND FILTERS AND CONTIGUOUS MULTIPLEXERS J 0 Rhodes and J E Dean* ABSTRACT A novel design and construction technique for Microwave Integrated Circuit broadband filters and a contiguous multiplexer is presented together with experimental results on a number of devices. The multiplexer is formed from a cascade of diplexers each containing a highpass and lowpass filter. Based on the ge

PSEUDO-ELLIPTICAL PHASE-EQUALIZED FILTER L.F. Franti* and G.M. Paganuzzi* AB ST RACT The paper considers a filter with double transmission zeros at both real and imaginary frequencies. The new approach allows satisfactory phase equalization for the stated out-of-band attenuation without increasing the filter degree as would be required for a linear phase filter. 

DESIGN AND PERFORMANCE OF FIN-LINE BANDPASS FILTERS by Abdel Megid Kamal Saad and Klaus SchUnemann ABSTRACT A transmission resonator implemented in fin-line technique is rigorously analysed by applying the method of equivalent rectangular waveguides. Based on these results, bandpass filters with up to 5 resonators are designed taking the higher-order mode coupling between the resonators int

WAVEGUIDE MULTIPLEXER WITH EIGHT CONTI GUOUS CHANNELS IN X BAND N. K. Andrzejewski, E. J. Pietraszewski + SUMMARY This paper presents theoretical and experimental work which was done upon a waveguide multiplexer with contiguous channels in 20 % frequency bandwidth in X band. The multiplexer consists of two branches joined by circulator. Each branch contains a piece of waveguide shorted at the

A NEW TYPE OF LOW LOSS FOR SATELLITE EARTH l4 GHz HIGH POWER COMBINING NETWORK TERMINALS J. Heierli*, K.R. Ainsworth* and G.J.P. Lo** C.M. Kudsia*, J. Dyrey*, /" ABSTRACT A High Power Combiner is described which provides equivalent performance at l4 GHz to that which is currently available at 6 GHz. This represents an advance in technology which is achieved through the use of: a) TEl13 Dua

A STRIPLINE FILTER DERIVED FROM DIRECTIONAL COUPLERS G. Saulich ABSTRACT A microwave filter consisting of two nonuniform-coupled transmission lines is presented. For this filter a synthesis procedure is described which reduces the design problem to the known synthesis of directional couplers. Examples of filters are calculated, a bandpass with equal-ripple behavior in the passband and stopba

THEORETICAL STUDY OF CIRCULAR WAVEGUIDE LATCHING PHASER K.P. Ivanov +) ABSTRACT The propagation of angular symmetrical TE mode in an infinitely long perfectly conducting circular waveguide, loaded with cylindrically stratified isotropic dielectric and latching ferrite, magnetised azimuthally to remanence, is studied theoretically. The transcendental characteristic equations of two remanent phaser



THE DESIGN OF PLANAR CIRCULATORS FOR BROAD-BAND OPERATION TANROKU MIYOSHI and SHINICHI MIYAUCHI ABSTRACT The stripline circulator used in MIC is considered one of ferrite planar circuits. We investigated the optimum shape and operation condition of the planar circulator for broad-band operation, perceiving the wider freedom of the planar structure in circuit design. The wideband planar c

A NEW NONRECIPROCAL FERRITE JUNCTION "M ~ J Maz-ur . K r - A new type of four-port nonreciprocal ferrite device which has features of the isolator, circulator and power devider is described. The nonreciprocal effects are due to the physical principles of the wave propagation in a ferrite stripline immersed into the bidirectional dc.magnetic field. An approximate analysis is presented with
