hi there,
can somebody tell me what is this port1, port2, port3, port4. i'm confuse which port is the power supply, is it port 1 or port 2.. or both are power supply ports. there was a phrase in this document stating
"The amplifier is keyed by applying 28 V to R1, this turns on the transistor. The collector can be left with 28 V also during receiving."
i don't understand this phrase above. can somebody explain to me. i also need to know which is the rfin and rfout ports. pls state to me which ports is it, is it port 3 or 4. i've put the circuit below with the ports on the diagram itself. i'm sure you guys out there can help me find the ports.pls help
