Hi...

very simple and cheep transceiver circuit without diversity!!!
And bad range... because diversity is very important in this frequency range.

Greetings from cold Germany

1 Impendance matching network (also BP)
2 l/4 line pin switch for RX/TX
3 RX divider to PMB6610
4 TX output approximately 25db/m
5 PMB6610 Low IF transceiver (RX/TX) with internal SAW filter network, Prescaler PLL, and internal
counter.
