GENERAL DESCRIPTION
The Instruments For Industry, Inc. ( IFI ) manufactured CMX25 Wide Band Amplifier is a
Bench Top or rack mount amplifier providing 40 Watts of linear RF power from 0.01 to 10000
MHz. The CMX25 incorporates two frequency bands of operation identified as Band 1 and
Band 2 which the CMX25 features easy operator frequency band switching without changing the
RF Output connections. The Band 1 frequency range is 10 kHz to 230 MHz with Band 2
frequency range being 200 MHz to 1.0 GHz. The minimum saturated output power over the
entire operating frequency range is more than 25 Watts.
The CMX25 features a Liquid Crystal Display ( LCD ) that displays continuous forward and
reflected power in four digit metering. The display also scrolls to provide the operator with
operating status and self diagnostic fault indications.
The CMX25 has an internal electronic gain control of 40 dB and a built in leveling control which
allows the CMX25 to level on an external controlling signal or level internally by an operator
determined the Automatic leveling Control ( ALC ) setting.
The CMX25 is unconditionally stable and incorporates protection circuits that monitors and
controls the VSWR input and outputs so the amplifier cannot be damaged by any mismatched
load.
The CMX25 has an optional IEEE-488 BUS interface which allows the amplifier to be remotely
controlled through the use of as computer and a GPIB BUS.
