CTO-565
Features
Description
Pin Configuration
• 1 Watt Output Power
The CTO-565 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 transistors and incorporates input/output blocking
capacitors, bias circuitry, 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.

Connector Option
For TC-1 case the only connector option
available is the -1. The -1 option consists
of a SMA Female connector on both the
input and output (see note).
Note: R-Series screening is not available in the TC-1 case as the case is non-hermetic.
