AMPLIFIERS

Solid-state Microwave Amplifier
The model 100S1G4 solid-state microwave amplifier provides 100 W minimum power in the 0.8 to 4.2 GHz range, which is used often in PCS, broadcast communications and other handheld wireless test applications. Local and remote control of the unit is available through its digital control panel (DCP). Additional DCP features include menu-assigned softkeys, a single rotary knob, four dedicated switches, gain control, internal and external automatic level control, pulse input capability and RF output level protection. An IEEE-488 interface is built in. An internal RF detector operates in self-testing and operational modes, and an extensive control and status reporting capability is available. A safety interlock can be implemented via a rear-panel connector. Price: $79,000.
