LNA Low Noise Amplifier Series
Preface
EMC (Electromagnetic Compatibility)
In accordance with European Directive 89/336/EEC, the LNA Modem has been shown, by
independent testing, to comply with the following standards:
Emissions:
characteristics of Information Technology Equipment.
(Also tested to FCC Part 15 Class B)
Immunity:
light industrial environment.
Additionally, the LNA has been shown to comply with the following standards:
IMPORTANT
•
Connections to the Tx and Rx IF ports (Type N or Type F connectors) should be
made using a good quality coaxial cable - for example 50 Ω or 75 Ω.
•
All 'D' type connectors attached to the rear panel must have back-shells that provide
continuous metallic shielding. Cable with a continuous outer shield (either foil or
braid, or both) must be used, and the shield must be bonded to the backshell.
•
The equipment must be operated with its cover on at all times. If it becomes
necessary to remove the cover, the user should ensure that the cover is correctly re-
fitted before normal operation commences.
