Product source ↗The Zetagi B-47 is a MosPower-series MOSFET RF amplifier for 26 to 30 MHz. It connects between a radio and its antenna system. Drive must remain within the specified range; maximum output depends on the supply, drive level and load.
The documented ratings distinguish AM/FM carrier power from SSB peak-envelope power. Electronic switching and reverse-polarity protection are included. The metal housing is cooled without a built-in fan.
