* Additional information is available from ACOM or from your dealer on how to interpret
these values. Using an EXCEL APPLICATION (available from ACOM or your dealer free of
charge) and a PC, you can decode these signatures by yourself.
In case it is necessary to ship the amplifier please see S.7-3.

7. SPECIFICATIONS

7-1. Parameters

a) Frequency Coverage: All amateur bands I.8-54MHz, extensions and/or changes on
request.
b) Power Output: I500W PEP or 1200W continuous carrier, no mode limit.
In continuous carrier modes (RTTY etc.) for transmissions longer than I5 minutes (up to
several hours depending on ambient temperature), the external auxiliary fan must be
installed.
c) Intermodulation Distortion: Better than 35dB below PEP rated output.
d) Hum and noise: Better than 40dB below rated output.
e) Harmonic Output Suppression:
I.8-29.7MHz - better than 50dB below rated output, 50-54MHz - better than 66dB below
rated output.
f) Input and Output Impedances:
- Nominal value: 50 Ohm unbalanced, UHF (SO239) type connectors;
- Input circuit: broadband, VSWR less than I.3:I, I.8-54MHz continuously (no tunings, no
switching);
- Bypass path VSWR less than I.I:I, I.8-54MHz continuously;
- Output (antenna) impedance matching capability: VSWR up to 3:I or higher.
g) RF Gain: 12.5dB typically, frequency response less than I dB (60-85W drive power for rated
output).
