Mirage B-320-G
The Mirage B-320-G is a VHF power amplifier designed for 2
meters covering 144-148 MHz. The “Hi” and “Lo” input selector
switch makes this amp useable for both handheld and mobile
transceivers. Features include all mode compatibility
(FM/SSB/CW), wrap-around heat sink, high gain GaAsFET
preamplifier, and user selectable input:
--”Lo” for Handheld radios-- 250 mW to 10 Watts
--”Hi” for Mobile radios-- 10 Watts to 50 Watts
FEATURES
1. High output power of 200 watts
200 watts is achieved with 250 mW to 10 Watts input
on “Lo” or 10 Watts to 50 Watts input on “Hi”.
2. All mode compatibility (FM/SSB/CW)
In the SSB mode the time constant of the Voice
Operated Transmit (VOX) 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. “Lo” Input power from 250 mW to 10 Watts
With an input power of 10 Watts maximum on “Lo” , the
Mirage B-320-G is compatible with most modern
handheld and mobile transceivers.
5. “Hi” Input power from 10 Watts to 50 Watts
