Abstract Broadband couplers consist usually of multiple coupled lines that are each a quarter wave‐length long. Herein, in contrast to conventional methods, a short length of a microstrip line is coupled to a coaxial line. The length of the coupled

Conventional broadband couplers use multi-sectioning techniques and consist of multiple coupled lines. In this study, in contrast to traditional methods, one pair of coupled lines is used to design multi-octave broadband couplers. In the proposed mic

In this paper, a broadband 30–1000 MHz power amplifier was designed. The results of simulation are compared with the measurements. In this work a commercially available LDMOS transistor (BLF645) is used. The amplifier can deliver 60W to a 50 ohm lo
