* For all states of refl ective switch in "ON" condition, "OFF port" 5:1 VSWR typ.
** Video leakage or break through is defi ned as leakage of TTL switching signal to
RF output ports
1. Absolute maximum power and voltage rating:
RF input power, 250mW
Supply voltage: 6V DC
2. OFF state of RF output is low impedance.
3. All RF inputs must be DC blocked or held at 0V DC
