1. During turn-on, the device requires an initial start up current (Icc) specified as "Turn-on Current". Once operational, Icc will drop to the specified levels. 2. The DC-DC converter is guaranteed to start µs as long as the power supplies have the maximum turn-on current available for start-up.GaAs SPDT Switch, Absorptive, Single Supply, - 4 GHz Pin Configuration 3,4,5
Parameter Max. Input Power 0.05 GHz - 4.0 GHz Bias Voltages VCC Control Voltage 8 Operating Temperature Storage Temperature Absolute Maximum +27 dBm +34 dBm -0.5V to VCC to +125°C
6. Operation of this device above any one of these parameters may cause permanent damage. 7. When the RF input is applied to the terminated port, the absolute maximum power is +30 dBm. 8. Standard CMOS TTL interface, latch-up will occur if logic signal is applied prior to power supply.
= No Connection 4. VEE is internally generated and must remain isolated from external power supplies. Generated noise is typical of switching DC-DC Converters. 5. Connections and external components shown in functional schematic are required. 0.1 µF Capacitors need to be located near pins & 26.
