abstract
A new compact, low-cost uniplanar impulse generator using coplanar waveguide structure has been designed, built, and tested. This uniplanar circuit consists of three functions: initial impulse generation, impulse amplification, and impulse compression, which are realized by a step-recovery diode and two-stage GaAs MESFET circuits, respectively. The impulse response has an amplitude of 2.3 V and a half-power pulse width of 115 pS. It has larger amplitude and narrower pulse width than the impulse generated by the SRD circuit alone.
