NOTES:
Operating Temperature, -40C to 85C
Storage Temperature, -55C to 100C
*
For all states of absorptive switch, and for reflective switch in "ON"
condition; for reflective switch "OFF" port, 5:1 VSWR typ.
** Video leakage or break through is defined as leakage of TTL
switching signal to RF output ports.
1. Absolute maximum power and voltage ratings:
RF input power, 250 mW
Supply voltage: 6 V DC
2. OFF state of RF output is low impedance.
3. Prices and specifications subject to change without notice.
