COM5000-8 POWER AMPLIFIER THE COM5000-8 IS A HIGH-EFFICIENCY CLASS AB AMPLIFIER WITH THE LINEARITY OF A CLASS A DESIGN. This amplifier is based on Silicon Power DMOS transistors that are specified for continuous operation (CW) at maximum rated power. The COM5000 is modular in design using basic building blocks in its four power amplifiers of 1.25 kW each. The output of each power amplifier passes through a selectable multiband low pass filter which is then summed by the output combiner. The amplifier incorporates a sophisticated microprocessor based controller which is used for normal “housekeeping” functions. The built-in T-4180 Exciter has RS-232 and RS-422 interfaces for connection to an external computer for remote control. Built-In Test (BIT) routines continuously monitor conditions within the amplifier and transmit status information upon request. The COM5000-8 has a built-in exciter (Cubic T-4180) and is FCC Part 87 certified.  www.cubic.com Enabling a Safer World • Modular Design • 5,000 Watts PEP and Average • 2.0 to 30 MHz • Automatic Level Control (ALC) • Operates into VSWRs up to 3:1 with graceful power reduction • VSWR Protection above 3:1 • Multiband Low Pass Filters • RS-232/422/485 Interfaces • Built-in T-4180 Exciter • FCC Part 87 Certified • Front Panel Forward and Reflected Power Meters Specifications • Frequency Range 2 to 30 MHz • Power Output 5,000 watts PEP and average (±0.5dB) with VSWR less than or equal to 1.3:1 • Power Input < 100mW PEP/average for rated power output • Input Impedance 50 ohm, 1.5:1 VSWR maximum • Gain Variation 1.5dB maximum over frequency range • VSWR Turndown Operates at reduced power from 1.3:1 to 3:1 VSWR Stable at any load; protected for infinite VSWR • 3rd Order IMD >32 dB below PEP • RF Noise At least 75 dBc/Hz below a 5 kW output reference level • Spurious Emissions -60 dBc or better within ±5% of the operating frequency.
