Mini-Circuits’ ZVA-18443VGX+ is a coaxial, wideband, variable gain, medium power amplifier with gain control, operating from 18 to 43.5 GHz. The model operates over a single supply range of +10 to +15 V, allowing users to choose their desired operating voltage. Internal DC-DC conversion circuitry maintains consistent efficiency over the full input voltage range. The amplifier incorporates a full suite of control and diagnostic tools, such as output power monitoring, amplifier fault tracking, internal temperature monitoring, enable/disable functionality for lower power consumption, and configurable digital or analog gain control.
The optional cable harness with integrated TTL to USB converter allows control of the amplifier from a PC moments after unboxing. Several DC-protection features such as over-voltage, reverse voltage, and in-rush current protection protect the amplifier from damage in case of unexpected spikes in voltage during operation. The high gain, low noise, medium power, and wideband frequency operation combined with digital control makes this amplifier an ideal choice for testing and instrumentation applications.
