Ophir 5022B

The Ophir 5022B is a Class A linear power RF amplifier engineered for broadband applications requiring high efficiency, reliability, and dynamic range. It delivers 50 W minimum output power across its operating band with +48 dB minimum small-signal gain and exceptional linearity—achieving +56 dBm typical IP3. The amplifier accepts CW, AM, FM, PM, and pulse modulated signals at input levels up to +10 dBm and maintains gain flatness within ±1.5 dB. Harmonics remain below −20 dBc typical at 35 W output, with spurious signals suppressed below −60 dBc typical.
