GENERAL DESCRIPTION
The PowerMax Innovation, Inc. ( PMI ) manufactured SOLID STATE Wide Band Amplifier is a
Bench Top or rack mount amplifier providing a nominal 50 Watts of RF power from 10KHz
to 230 MHz, with output power of at least 50 Watts. The minimum saturated output power
at midband of the operating frequency range is more than 50 Watts.
The Amplifier features a touch screen 7” high resolution [800x480] color TFT Display that displays
continuous forward and reflected power metering. The display also provides the operator with operating
status and self diagnostic fault indications.
The Amplifier incorporates protection circuits that monitors and controls so the amplifier cannot be
damaged by any mismatched load.
The Amplifier has an Ethernet interface which allows the amplifier to be remotely controlled through
the use of a computer.
To operate the Amplifier, connect a single phase power line cable (220 Vac line to Neutral) 3 wires to
the Power Entry connector on the rear panel.

GENERAL INFORMATION
4.1 SCOPE OF THIS MANUAL
This manual is intended to inform a qualified transmitter operator or technician of the normal operating
and maintenance procedures for this Amplifier. It is not intended to be a course of instruction for
unqualified personnel.
4.2 OPERATION OVERVIEW
The Amplifier is designed to amplify a low level microwave signal and supply a high power CW output.
The Amplifier system function is accomplished primarily through the use of a High Power RF Module,
control circuitry and power supplies, which can be controlled either locally or remotely. The control
circuitry and the power supplies are mounted on the top deck. All the RF components which include the
divider, combiner, couplers and High Power RF module are mounted on a heat sink on the bottom deck.

4.4 GENERAL SPECIFICATIONS
The specifications listed below represent the minimum performance characteristics at the time of
delivery.
SPECIFICATIONS
Frequency Response 10KHz to 230MHz
Power Output: Minimum 50 Watts
Power Gain: 47 dB
Input Impedance: Nominal 50 Ohms
Output Impedance: Nominal 50 Ohms
Input Signal Levels: < 0 dBm (1.0 mW) See data sheet for RF input drive levels
Duty Factor: CW
Prime Power: 220VAC, 50/60 Hz, single Phase, 3 Wires
Power Requirements: 1KVA
Functional Description
The required voltages and currents to operate the amplifier are provided by the main 48VDC supply.
The primary control circuitry and the service power supplies (+5V, +/- 12V, + 24V) are energized when
the main circuit breaker is turned ON. Upon pressing the RF ON switch, the main 48V power supply is
energized and the RF Modules are enabled and biased. At this stage when RF power drive is applied to
the RF-Input connector the RF power will be amplified and will be displayed on the TFT display.
4.5 PROTECTION CIRCUITS

MAN-70009, REV A Page 17 of 35
The SOLID STATE Amplifier is designed with a variety of protection circuits to provide safeguards for
the amplifier should any adverse electrical conditions occur or if the amplifier is accidentally
experiencing operator deviation of the design application. Listed below are the safeguards.
4.5.1 Over Heat Protection
The SOLID STATE critical components of this Amplifier is mounted to a heat sink which in turn, air
cooled by high efficiency blower. Should an over heating condition occur, either through component
failure or by a restricted air flow, the Amplifier contains heat sensors that will shut down the system
should an over heating condition occur. As a result, the air inlet and outlet openings should be free of
obstructions for proper cooling of the amplifier. Operation is restored by the Fault/Reset button when
the amplifier cools to normal temperature levels.
4.5.2 PA Module Over temperature Fault
The PA modules have internal temperature monitoring which is displayed on the Color display [the
display will only show the temperature of # of modules used]. If the temperature in any modules rises
above the set limit the amplifier will revert to Standby and the Fault Indication on the front panel
Display of the Amplifier will display the related fault.
4.5.3 Mismatch Protection
The Amplifier is designed to operate with a tuned 50 Ohm load and should any mismatching of the 50
Ohm occur the Reverse Power, also called Reflective Power, will increase producing a high VSWR.
The Amplifier microprocessor monitors the Reverse Power levels by utilizing a Dual Directional
Coupler. When the Reflected Power exceeds 25% the Amplifier Output Power it will go to STBY and
the High VSWR message will be indicate on the TFT display. The Reverse Power is also displayed on
the TFT Display for operator monitoring for any mismatched load.
4.6 STATUS INDICATORS, CONTROLS AND CONNECTORS
The Amplifier has various controls and status indicators which are identified below and can be visually
located on Figure 6.0, Illustration and Figure 11.0, Rear Panel Illustration. A narrative description for
the function and purpose of each control and status indicator is provided within paragraphs 4.7 and

4.7 FRONT PANEL STATUS INDICATORS
INDICATOR FUNCTION
Fault The Fault will be indicated when the main Power Supplie deviate from the
design parameters. The Amplifier will revert to RF OFF mode. When
either a Thermal condition occurs outside design parameters. Should an
excessive temperature condition occur while monitoring the SOLID
STATE temperature of the Heat sink temperature the Amplifier will revert
to RF OFF mode. Also when an RF module failed. The TFT Display will
indicate which fault had occurred.
Total/RFON HOUR Elapsed time Indication on the TFT display, presents total hours that
the amplifier total or RF-ON has been energized.
Remote The Remote will be indicated when the amplifier is in the remote control
mode of operation via the computer.
4.7.1 CONTROLS
CONTROL FUNCTION
Power ON / OFF Circuit Breaker to turn On/Off main prime power to the Amplifier.
Local The Local switch is a momentary switch. When
depressed, the amplifier is restored to the local control from the
Remote mode of control.
RF OFF / RF ON Switch, when set to RF ON mode it will apply DC Voltage to the RF
Modules, when set to RF OFF it turn RF Modules OFF.
RESET Switch, when pressed resets Faults.
