HP / Agilent 8447E 0.1-1300 MHz power amplifier; 115/230 V

The HP/Agilent 8447E is a solid-state power amplifier spanning 0.1 to 1300 MHz, delivering 22 dB ± 1.5 dB mean gain with ± 1.5 dB flatness across the full frequency range. Built on thin-film hybrid integrated circuit technology and hermetically sealed for reliability, It has output power ≥ +12.5 dBm at 1 dB gain compression (0.1 to 1000 MHz) with harmonic distortion of -30 dB at +10 dBm output. The amplifier exhibits low noise performance ( 40 dB), and VSWR < 2.2 across 1 to 1300 MHz, making it suitable for signal boosting in test, measurement, and communication applications. Hermetic construction ensures performance stability across 0°C to +55°C operating range. The 8447E accepts 115/230 VAC ±10%, 48–440 Hz input with 15 W power consumption and standard 50 Ω BNC connectors (Type-N optional).
