I have a project that I am working on that requires me to be able to control the state of a Coax or BNC Connector connected between a satellite receiver and LNB(Dish). The cable is rated at 75ohm, carries 18v DC and a freq of up to 3GHz. This circuit is not to split a satellite signal but to simply connect/disconnect the receiver/line from the LNB with little to no loss in voltage or signal.
I am using a ATmega328P to 74HC595 8-Bit Shift Register to control multiple connectors. However, I am unsure which transistor, if any, will support the cable ratings I need with little to no loss if possible.
If that is not possible, would anybody have any ideas how else I could control the connectors?
Thanks.
