TRANSFER SWITCHES
0.025 - 18 GHz
GENERAL INFORMATION
Series DTS transfer switches allow power entering two input ports, A
and B, to exit from output ports C and D respectively, or by appropriate
switching, to exit from ports D and C respectively. A functional schemat-
ic of a transfer is shown in Fig. 1, and a typical circuit is shown in Fig. 2.
