QMODP0A Standard Q-Switch 20W


These drivers based on quartz oscillators, produce a fixed stable and accurate RF frequency signal. The built in amplifier delivers the necessary RF power to drive an air cooled Q-switch up to 20 W.

The RF output power can be externally modulated with a TTL and an analog 0-5V signal. Standard output power is up to 20W, but can be reduced on request. Standard power supply is 24VDC.
