»Reference Class from DC to 200 MHz

Offset adjustable by trimpot or external control voltage. Indication of selected gain setting by LEDs. Output short-circuit protected. Power supply via 3-pin Lemo® socket. A mating connector is provided with the device. Optional power supply series PS-15 available. For further information please see the datasheet.

The new improved models DHPVA-101 and DHPVA-201 replace the previous models DHPVA-100 and DHPVA-200. They are fully compatible delivering at least the same or better electrical performance. The heatsinks may be removed if adequate alternative cooling is provided like mounting the amplifier to a sufficiently large case/rack system.
