This paper illustrates the design and development of L-Band GaN based high power, high efficiency pulsed transmitter to deliver peak output power of 50W at centre frequency of 1.25 GHz with 75 MHz bandwidth. This L-Band transmitter has been designed and developed for dual frequency (L&S-Band) airborne SAR mission. Size, weight and power constraints led to the selection of GaN HEMT devices which offer inherently higher efficiency compared to GaAsFET devices. Class-F approach has been used for… Expand
