/ COMMUNICATIONS Employee Owned Company USER MANUAL SR SERIES CONTINUOUS DUTY UHF RF POWER AMPLIFIERS 3370 SAN FERNANDO RD.
PRODUCT DESCRIPTION The SR series of TPL Power Amplifiers are intended for use in base station or repeater applications. They are all medium power units (100 watt range) and in various configurations will cover the frequency range extending from Low Band VHF to 960 MHz. An SR amplifier is a containerized unit which is designed to be installed in a 19-inch rack. Four options are available, depending upon the customer's primary power and cooling requirements.
OPTIONS TPL Communications’ UHF Continuous Duty RF Power Amplifiers are available with several options: input, output, voltage, frequency ranges, and configurations, special logos, etc., when specified at the time of order. We work closely with you, our customer, to develop products that are in complete compliance with your needs and specifications. PACKAGE OPTIONS: -SRXRF: Extruded aluminum heat sink with alarms, protections and cooling fan.
CAUTION! Inspect the amplifier upon receipt for visible damage. If any is noticed, please call TPL Communications at 800 HI POWER to request an RMA (Return Material Authorization) number. If purchased through a dealer or distributor, ask them to also follow this procedure for best results. EXPENSIVE COMPONENTS MAY BE DESTROYED IF THE AMPLIFIER IS TURNED ON IN A DAMAGED CONDITION.
GENERAL SPECIFICATIONS CONTINUOUS DUTY UHF POWER AMPLIFIERS FREQUENCY RANGE: 400 512 MHz TABLE 1 MODEL POWER POWER DC SUPPLY INPUT OUTPUT CURRENT VOLTAGE PAB-1EE-SRXRF-PS 50-260 mw 100 W 24 Amps. 13.8VDC PAB-1AE-SRXRF-PS 24 WwW 100 W 20 Amps. 13.8 VDC PAB-1AE3-SRXRF-PS 4-8 W 100 wW 20 Amps. 13.8VDC PAB-1BE-SRXRF-PS 8-15 W 100 W 16 Amps. 13.8VDC PAB-1FE-SRXRF-PS 15-30 WwW 100 W 18 Amps. 13.8 VDC 1.

GENERAL SPECIFICATIONS (continued) CONFIGURATION: Repeater configuration is standard and it is supplied without a SSR. Base station configuration is optional and it is supplied with SR. The separate RX Port is optional. CIRCUIT PROTECTION: Provided by a circuit breaker with model-dependent current rating. OPERATING TEMPERATURE RANGE: -20° to +50° Celsius. STORAGE TEMPERATURE: -40° to +85° Celsius.
OPERATING PRECAUTIONS CAUTION: This amplifier produces RF voltages that can cause painful and dangerous RF burns. Use caution! Connect and disconnect all RF connections with the DC power and drive power off. DRIVE POWER: RF power transistors, although quite rugged in most respects, are easily damaged by overdrive. Be careful not to overdrive this amplifier, even for an instant. Higher than rated drive power may destroy the transistors and VOID ANY WARRANTY.
Indicator SYSTEM INDICATORS Function/Characteristic Steady Green LED indicating that DC Voltage is being applied to the amplifier. . Steady yellow LED indicating that adequate RF drive power is being applied to the amplifier. Flashing red alarm LED when RF output power is below an internally preset level. Flashing red alarm LED when output load SWR exceeds the internally preset level. Flashing red alarm LED when amplifier heat sink temperature is above an internally preset level.
OPERATOR ADJUSTMENTS The operator adjustments are accessible on the back between the RF connectors. These are turn potentiates P1 through P5 and switch SW1. Their functions are as follows: Ref. Des. Function / Adjustment P1 Determines the threshold for a valid input RF power level. P2 Low RF power output threshold set to determine the alarm level for the front panel indicator. P3 Sets the RF output power level under RF feedback leveling control.
REMOTE MONITORING The monitored functions are described in other sections. These same functions, some of which are displayed by LED's on the front panel, are available at the REMOTE MONITOR DB-15 connector on the rear panel. The outputs are as follows: Monitor Signals Function | Pin | Signal Definition Source Mode | Voltage Current VCC 1 [+5 Volts Reference Supply |+5 VDC 20 mA Max. +8 VDC 2 |+8 Volts Regulator Supply |+8 VDC 20 mA Max. Active LPA 3 | Low Power Alarm Open Collector Low 30 V Max. {20 mA Max.
