OPERATING THE TRANSCEIVER
USING AN EXTERNAL POWER AMPLIFIER
118 ENVOY® TRANSCEIVER GETTING STARTED GUIDE
Using an external power amplifier
Overview of the 3061 & 3062 power amplifiers
The 3061 and 3062 power amplifiers provide 500 W PEP and 1000
W PEP output power respectively, and are suitable for voice and
data operation.
NOTE: Codan’s power amplifiers are fully protected against
all load conditions and excessive heat sink
temperatures. They are capable of operating with a
VSWR of up to 3:1 by reducing output power. When
excessive VSWR or over temperature occurs, the
amplifiers switch to by-pass mode in order to prevent
permanent damage.
NOTE: In by-pass mode, the full output power of the
attached Envoy® transceiver is available as a backup
to keep the station operational and on-air.
The external power amplifier is connected to the Envoy®
transceiver through the Antenna Control cable (08-05627-00x). In
order to transmit with the external power amplifier, you need to set
the Tx power setting to PA.
Inspecting the status of the power amplifier
The Envoy transceiver enables a user to easily inspect the operating
status of a connected power amplifier. It retrieves the runtime
status information from the power amplifier and presents it to the
user after every transmission.
