The Mini-Circuits ZVE-3W-83+ is a high-power wideband RF amplifier delivering 30–40 dB gain across the 2000–8000 MHz band. Built for signal amplification in demanding transmission and communication systems, it provides +31.5 to +33 dBm output at 1 dB compression and +33.5 to +35 dBm at 3 dB compression. The amplifier operates from a 15 VDC supply with internal regulation across 13–18 VDC input, drawing a maximum of 1.5 A. Input and output VSWRs are 1.5:1 and 1.4:1 typical, respectively, with a noise figure of 5.8 dB and third-order intercept point of +42 dBm typical. Gain flatness remains within ±1.15 dB typical (±2.0 dB maximum) across the operating band.
