I need to design a DP8T microwave switch for a microwave imaging senior design project. The frequency range is 2 to 6 GHz.
I need to switch between 8 antennas and a 2 port VNA. So each antenna transmitting and receive one at a time. I'd imagine this is a common problem in RF engineering, but I can not find an IC chip or a commercial solution that is 2X8.
Switching time: Doesn't matter
Power: 16 dBm
Insertion Loss ~ .8 dB
Isolation > 30 dB
Control signal: TTL or CMOS
Above all, I will settle for anything that can work. I want to have a start at something even if I can improve later. My budget is very limited, even though I have access to PCB printing and lab equipment.
