The 5258 from Ophir RF is a Solid-State Power Amplifier that operates from 1000 to 2500 MHz. It delivers a saturated output power of 1000 W with a small signal gain of more than 60 dB. This Class A amplifier utilizes Gallium Nitride (GaN) technology that provides high output power, VSWR tolerance, and a wide dynamic range. It uses advanced devices and components to achieve high efficiency and reliability and supports CW/AM/FM/PM/Pulse input signal formats. The SSPA has automatic leveling control allowing end-users to maintain a steady output even with variations in temperature or the RF input level. It has spurious levels of -60 dBc and minimum harmonics of -15 dBc.
The 5258 features built-in over-current, over-voltage, and thermal over-load protection circuits to prevent short-circuit related damages. It allows users to monitor forward and reflected power, provide gain control of 20 dB, control remotely via Ethernet, RS-232, or IEEE-488 communication ports, and locally view the system status using the front panel display. This amplifier is available in an enclosure that measures 19.0 x 14.0 x 24.0 inches with N-type and 7/16 DIN input/output connectors. It requires an AC supply of 208 V and consumes less than 4500 W of power.
