Abstract: The design of strip Blumlein line was presented with the polymer-composite as energy storage dielectric and GaAs-PCSS as circuit switch.The experment results show that relative permittivity of the polymer-composite reaches 80~250, the permittivity and susceptibility of the dielectric do not change under different voltages.The risetime of voltage pulse of the strip Blumlein line is less than 5 ns, the flat top is about 22 ns with ripples of flattop about ±1%. The designed Blumlein line can satisfy the needs of application.-
