Mini-Circuits Connectorized SMA, High Power, Linear Amplifier, 20 MHz to 1000 MHz, 50Ω ZHL-20W-13+

The ZHL-20W-13+ is a high-power coaxial amplifier designed for 50Ω systems, operating from 20 to 1000 MHz with a nominal output power of 20 W. It features a case style CP641 with SMA connectors, a gain of 46 to 55 dB, and a gain flatness of ±1.8 dB. The device operates from a 24 V DC supply, drawing 2.8 A, and includes automatic overheat shutdown. The base plate temperature must not exceed 85°C, requiring an external heat sink with thermal resistance no greater than 0.38°C/W. Operating temperature ranges from -20°C to +65°C. Input and output VSWR are 1.7:1 and 2.5:1 respectively. Output third-order intercept point is +50 dBm, with a noise figure of 3.5 dB. The amplifier is protected by US patent 7,348,854 and is not designed for open-load conditions.
