Hi,
Initially We designed a board for 2-6 GHz band application. It used 4-Layer FR4 PCB material.
Its performance in 4-6 GHz band was very worst. It had very high dielectric losses at such high frequency.
Taking into account this consideration, now We have optimized the design.
We are planning to use hybrid stack-up ( Rogers R04003 8 mils + FR4).
Will this will reduce the dielectric losses at high frequency ?
Will this hybrid stack-up hamper the performance of board ?
Please help.
Thanks,
CR
