Mirage B-34-G
The Mirage B-34-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 1 to 8 watts input.
FEATURES
1. High output power of 30 to 35 watts.
30 to 35 watts is achieved with 1 - 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 1 to 8 watts
With an input power of 8 watts maximum, the Mirage
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

EXPLANATION OF FEATURES
FRONT PANEL
1. ON AIR PILOT LAMP
The ON AIR pilot lamp indicates the amp is
transmitting
on the air.
2. PRE-AMP PILOT LAMP
The RX pilot lamp will illuminate when the pre-amp is
engaged. The pre-amp can be used independently
even
if the amplifier's power is off.
3. POWER ON PILOT LAMP
If the lamp is in the off position the amplifier will pass
the RF in a straight through mode. This means that
both the receive and transmit signal will bypass the internal

circuitry of the amplifier. If the lamp is illuminate then
the amplifier is in the standby mode and will amplify
any
signal that is supplied to its input of more than 1 watt.
