Mirage B-310-G
The Mirage B-310-G is a VHF power amplifier designed for the
144-148 MHz band. New features make it the most useful and
versatile amplifier available for the handheld transceiver.
Features include all mode compatibility (FM/SSB/CW), wrap-
around heat sink, high gain GaAsFET preamplifier, and 25O mW
to 8 watts input.
FEATURES
1. High output power of 100 watts
100 watts is achieved with 250 mW to 8 watts input.
2. All mode compatibility (FM/SSB/CW)
In the SSB mode the time constant of the Carrier
Operated Transmit (COX) relay is set to approximately
one second to prevent annoying relay chatter
during conversation, and achieving smooth SSB
transmission.
3. Wrap-around heat sink
The heat sink and combined case, by original design
is used for excellent heat dissipation as well as a
new smart appearance.
4. Input power from 250 mW to 8 watts
With an input power of 8 watts maximum, the Mirage
B-310 -G is compatible with most modern handheld
transceivers.
5. GaAsFET receive pre-amplifier
A built-in low noise GaAsFET receive pre-amp enables you
to enjoy a more comfortable VHF QSO with weak
stations.
