MIRAGE BD-35

DUAL BAND POWER AMPLIFIER

INTRODUCTION:

The Mirage BD-35 is a 45/35 watt dual band power amplifier for use with
today's dual band handie talkies operating in the 144/440MHz bands. W e
have succeeded in the development of a cros s-band full duplex func tion and
have incorporated it into this design. The compact design of the power
amplifier unit employs the new "two band / one RF power transistor"
technique. The BD-35 is a

remarkable

and

useful

dual band power amplifier

for the

discriminating

Amateur Radio operator.

FEATURES:

•

High output power

Up to 45 watts at 144MHz or up to 35 watts at 440MHz. 30 to 35

watts is achieved with 2 to 6 watts input.

•

Input power from 0.3 to 7 watts

With an input power of 7 watts m aximum, the Mirage is compatible

with most modern hand-held tranceivers.

•

Small size

This amplifier's size mak es it the perfec t com panion f or f ield operation

without the added weight.

•

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.

•

Reverse DC power polarity protection circuit

Protects the amplifier from accidental reversing of the power leads.

•

"ON-AIR" indicator

Lets you know that you are transmitting.

EXPLANATION OF FEATURES:

••••

VHF ON AIR LAMP

This LED indicates that the power amplifier is transmitting in the VHF
(144 - 148MHz) band.

••••

UHF ON AIR LAMP

This LED indicates that the power am plifier is transmitting in the UHF
(430 - 450MHz) band.

••••

POWER ON LAMP

When the power switch is engaged the amplifier will illuminate the

POWER ON

lamp. This lets you know that the amplifier is ready to

amplify any signal of the proper frequency applied to its input.

••••

ANT (RF OUTPUT)

The coax from your antenna is connected to this port.

••••

RADIO (RF INPUT)

The coax from your radio or exciter is connected to this port.

••••

DC PWR (13.8V)

This port has two wires. The

Red

wire is for positive and incorporates a

FUSE holder. The

Black

wire is for negative. The Mirage BD-35

amplifier will accept from 12 to 15 Vdc.
