Abstract
High power jammer systems are widely used in today's electronic warfare, such as CREW, WARLOCK, Rubicons II. To paralyze enemy's communication completely, the high power jammer system should block the frequency range from MHz up to GHz, with high efficiency high linear power amplifiers. The "Extremely Broadband Power Amplifier (EBPA)" covers frequency ranges from HF to C-band, making it an excellent candidate for jammer applications, The EBPA uses broadband high power MMICs, developed by Rockwell Collins, a team member. Broadband MMICs using wide bandgap devices, capable of provide 10W at HF to more than 30 W at C-band, a broadband amplifier covering frequencies from HF to C-band will be designed. The devices will be configured in a balanced push-pull configuration to achieve great VSWR handling ,and excellent 2nd harmonic suppression of greater than 40 dBc. When combined using our novel broadband combiner techniques, power levels of 150W with efficiency values greater than 40% is expected. In our efforts, the power combining will be split into three frequency divisions: HF to UHF, UHF, and L-band to C-band. For frequency ranges from HF through UHF, ferrite loaded coaxial combining techniques will be utilized.
