For my present project, I need a RF transmitter and a matching reciever, to trigger something very time important. I dont need to transmit any data. Simply a signal that is there or not there, or a loginc "1" or "0" every second or so. The problemm is, that the signal must be strong enough to pass easily through some solid walls, and it must be countinous. I dont want any discrete logic refreshing with 10Khz or something like that. I want a analog circuit, that responds continuesly to the transmitter. So If I compare the input "1" with the responding output "1" of my reciever on an oscilloscope, there must always be the same time difference. Apart from that the transmitter and the reiciever must work very responsive. (total time of signal transmission should not exceed 1ms) Do you know any IC or circuit which would match my needs? (I am thinking in 300-1000Mhz range) Instead of a normal RF - Signal with fixed frequency, I was also thinking about an elctromagnetic pulse, which is powerfull enough to be sensed through a couple of walls. - but I think I might get problems woth other elctronical devices near by. I have already tested mainstream ASK 433Mhz rf modules under my oscilloscope, and as expected the time difference alternates, because of their discrete digital sensing.
Thanks in advance!
