MIRAGE BD-38-G Dual Band Amplifier

 

MIRAGE BD-38-G 

DUAL BAND POWER AMPLIFIER 

INTRODUCTION: 

The Mirage BD-38-G is a 80/60 watt dual band power amplifier for use with today's 
dual band handie talkies operating in the 144/440MHz bands.  We have succeeded in 
the development of a cross-band full duplex function and have incorporated it into 
this design.  The BD-38-G is a 

remarkable

 and 

useful

 dual band power amplifier for 

the 

discriminating

 Amateur Radio operator.  This compact dual band power 

amplifier has two independent GasFET pre-amp for VHF and UHF bands. 

FEATURES: 

• 

High output power 

 

Up to 80 watts at 144MHz or up to 60 watts at 440MHz.  Output is achieved 
with 2 to 5 watts input. 

• 

Input power from 0.25 to 5 watts. 

 

With an input power of 5 watts maximum, the Mirage is compatible with most 
modern hand-held tranceivers. 

• 

Automatic Frequency selection and control circuit.  This allows the amplifier to 
have only one input connector and makes for a perfect match for today's dual 
band radios and dual band antennas. 

• 

Separate VHF and UHF Pre-Amps. 

• 

Separate LED Indicators for VHF and UHF Pre-Amp usage. 

• 

LED Bargraph Power Level indicator. 

• 

Hi-SWR and Over Temperature Protection. 

• 

Patch Cable included (BNC to PL-259). 

• 

Input: 13.8 VDC at 15 amps. 

• 

Size: 6.5” W x 2.5” H x 9” D 

• 

One Year Warranty
