Preamplifier 100kHz-1.3GHz, option: H64 = Low frequency preamplifier 9kHz-50MHz, type- N connectors

The HP (now Keysight) 8447D (Preamplifier, 25 dB gain), 8447E (Power Amplifier, 22 dB gain)and 8447F (combined) are genaral purpose, wide band amplifiers.

Each instrument consits of a power supply and one or two thin film, hybrid, integrated circuit amplifiers. The thin film amplifiers are hermetically sealed and feature low noise, low distortion, flat frequency response, and long therm stability and reliability.

The HP (now Keysight) 8447F Amplifier contains a preamplifier and a power amplifier.

They are the same thin film amplifiers used in the 8447D and 8447E.

The input and output ports of both amplifiers are available on the front panel.

They can be used separatlely or cascaded to provide 47 dB of gain.

The 8447F option H64 Amplifier is a general purpose wide band amplifier with type-N connectors. It contains two preamplifiers. One provides 26 dB min. gain to signals from 9 kHz to 50 MHz. The other provides 25 dB min. gain to signals from 100 kHz to 1300 MHz.
