VZM-2780C2

s
M-Band
500 W Rack-Mount TWTA
Compact
Provides 500 watts of power in the 8.0 to 18.0 GHz
frequency band in a compact 19-inch rack-mount dual
drawer configuration for wideband testing.
Efficient and Reliable
Employs CPI dual-depressed collector helix traveling
wave tubes, increasing efficiency by a nominal 20% over
conventional single collector TWTs, and a power supply
designed with a minimum number of parts for
maximum uptime.
Simple to Operate
Integrated microprocessor control lets the user adjust and
monitor all operating parameters from one easy-to-read
local or remote panel, using straightforward menu-driven
commands. Includes a built-in interface and serial bus for
operation from the station computer.
