WIDEBAND PULSE AMPLIFIER F. Meyer ABSTRACT In order to build a Gigabit/s pulse amplifier for medium power applications a new transistor distributed amplifier configuration was developed and tested. The amplifier is built in hybrid technique empolying 5 GHz fT bipolar transistors. The five section amplifier has a frequency response from DC to 3.6 GHz. Results achieved were a 10 dB gain, 130 ps st

McElhone, ABSTRACT The use of R.F. transistor power amplifiers under multicarrier operating conditions in satellite transponders can create reliability problems incompatible with a long mission life, due to the high instantaneous volta





CYLINDRICAL DIELECTRIC RESONATORS AND THEIR MICROWAVE CIRCUITS M. W. Pospieszalski APPLICATIONS IN TEM-LINE ABSTRAC'l' A cylindrical sample of low-loss, high-r dielectric placed between two parallel conducting plates perpendicular to the sample axis forms microwave resonator. A simple approximate method for predicting the resonant frequencies of the TE modes of this structure is developed. The

MODIFIED COMMUTATING NETWORKS FOR MULTIPLEXING AND RECEIVING APPLICATIONS IN TRANSMIT M.J. Adams, C.S. Barham, I. L. Powell, B. K. Watson ABSTRACT The response of the simple line length diplexer can be significantly improved by the addition of two all-pass networks. Using pairs of short-circuited standard waveguides, flat equally-spaced passbands with narrow guard bands can be realised. A furth

INTERACTING STEP DISCONTINUITIES IN PLANAR DIELECTRIC WAVEGUIDES Tullio E. Rozzi ABSTRACT Planar dielectric waveguides play an important role in electro-optics. In many laser configurations and integrated optical components, grooves are etched in the planar surface or overlays are deposited on it. The step is an idealization of such a discontinuity. This paper has two aims. First, the fiel

MODELING AND APPROXIMATION FOR STATISTICAL MICROWAVEDESIGNS EVALUATION AND OPTIMIZATION OF J.W. BANDLER AND H.L. ABDEL-MALEK This paper shows how, by suitably updated approximations, one may surmount the obstacle of expensive experimental tuning or repeated computer simulations of trial designs when optimal designs or statistical analyses are required. The authors address themselves to the e
