The Mini-Circuits ZVE-3W-83+ is a high-power wideband amplifier delivering 3 W output across 2–8 GHz with 30–40 dB gain and exceptional linearity. Built for demanding RF and microwave systems, it combines high gain flatness (±1.15 dB typical), output IP3 of +42 dBm typical, and low noise figure of 5.8 dB typical. The unit operates from a single +15 V DC supply at 1.5 A maximum and maintains performance across –40°C to +85°C base-plate temperature with external heat-sink management.
