Mini-Circuits ZVA-50953X+ is a coaxial wideband and flat gain amplifier operating from 45 GHz to 95 GHz. The model operates over a positive supply range of +10 to +15 V, allowing users to choose their desired operating voltage. Internal DC-DC conversion circuitry maintains constant efficiency over the full input voltage range. The amplifier incorporates several DC-protection features such as over-voltage, reverse voltage and in-rush current to protect from damage in case of unexpected spikes in voltage during operation.
