Empower RF Systems Announces the GCS3J3QQN, a Next Generation HDTV Translator Unit
for Broadband HDTV (8VSB) Transmissions
200W HDTV
system
The GCS3J3QQN is a next generation HDTV Translator unit for broadband HDTV
(8VSB) transmissions. This translator utilizes push-pull LDMOS power devices and Active Device
Bias Control TM via Microprocessor that provide high gain, wide dynamic range, low phase
distortions and excellent linearity. The translator unit is designed as a flexible compact
system which can be scaled accordance with the required output and application.
