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
