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

SWR LED This LED will turn ON if the SWR of the antenna used is too high. When this light is on, there will be no amplified output from the BD-38-G due to the protection circuit inside the amplifier. Back Panel •... - Page 4 MIRAGE BD-38-G Dual Band Amplifier INSTALLATION AND OPERATION: The Mirage BD-38-G may be mounted using the bracket (not supplied) or simply placed in a convenient operating position. In either case, there must be adequate ventilation for the finned heat sink. This generally means at least 1 inch clearance from the heat-sink to any surrounding enclosure and an unobstructed flow from the front to the back of the heat sink.
