High Efficiency, Class A, 1 Watt Amplifier 10 to 1000 MHz Technical Data CTO-1065
Features
Description
Pin Configuration
• 1 Watt Output Power
The CTO-1065 is a high gain, high efficiency , Class A 1 Watt amplifier designed to provide broadband power for a wide variety of applications. This two stage hybrid amplifier uses silicon bipolar and incorporates input/ output blocking capacitors, bias network, and is matched to 50 Ω for easy integration with other components (no external components required for operation). Available packaging for this unit is the industry standard TO-3 case.
