The Mini-Circuits ZFL-1000VH is a broadband medium-power RF amplifier spanning 10 MHz to 1000 MHz, engineered to deliver high gain with excellent linearity and low noise in a compact shielded coaxial package. The device operates at 50 Ω impedance and reaches +25 dBm output power at 1 dB compression, making it ideal for signal amplification across cellular, VHF/UHF, and test equipment platforms. Gain flatness of ±1.0 dB and a noise figure of 4.5 dB typical support demanding instrumentation and communication applications. External heat sinking is required to maintain case temperature below 71°C.
