I plan to setup the TLP-434A type modules with a xmtr and rcvr that share a common antenna, running half-duplex on the same frequency.
I have a design (only on paper) that does T/R switching using a pair of PIN diodes, an inductor, a couple of C's, and a couple of R's. A PIC will be available to do the T/R switching, so it's not necessary for it to be 'automatic'.
Has anyone tried anything similar?
Is there a simpler way that is effective?
Given that the xmtr is rather low-power, is there any danger of damaging the front end of the rcvr?
Thanks,
Pete
