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. © 2003 Wiley Periodicals, Inc. Microwave Opt Technol Lett 39: 470–472, 2003
