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:
NOTE:
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.

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.
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.
