 PRODUCT DESCRIPTIONThe PA1-1AEM model is a mobile  VHF low band RF power amplifier intended for use in the mobileapplications. This amplifier can deliver RF power from 60 to 110 W when driven with 2 to 4 W and itwill cover the frequency range from 36 - 42 MHz. The mobile amplifier is designed to be installed inthe interior of a car or in the trunk. The amplifier’s dimensions are: 11.6"L x 3.0"H x 5.5" W(see figure 1) and the weight is 5 lbs.Figure 1. Dimension (D package). GENERAL SPECIFICATIONSThe general specifications for the PA1-1AEM amplifier are shown in this section.TABLE 1FREQUENCY BAND: 36-42 MHzOPERATION MODE: FM / CWOPERATING VOLTAGE: Nominal DC operating voltage is 13.8VDC and the specifications aregiven at this voltage. However, the minimum DC operating  voltage is 11 Volts and the maximum DCoperating voltage is 15 Volts as measured at the VDC input connector. Reduced DC input voltage willresult in lower output power and efficiency.EIA DUTY CYCLE: WITH NO EXTERNAL COOLING:110 W Output (FM) 30% duty cycleNOTE: Use of TPL Mobile Amplifiers above the recommended duty cycle or in repeaterapplications is not recommended and voids the warranty.Page 2LEDOMTUPNIREWOPTUPTUOREWOPLANIMONTNERRUCLANIMONEGATLOVESUFMEA1-1APW4-2W011-06A91CDV8.31A03

We work closely with you, our customer, to develop products that are in complete compliancewith your needs and specifications.CAUTION!Inspect the amplifier thoroughly upon receipt for visible damage. If any is noticed, please call TPLCommunications at 800 HI - POWER to request an RMA (Return Material Authorization) number. Ifpurchased 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 ONIN A DAMAGED CONDITIONPage 3
OPERATING PRECAUTIONSCAUTION:This amplifier produces RF voltages that can cause painful and dangerous burns. Use caution!Connect and disconnect all RF connections with the drive power and DC power off.DRIVE POWER:RF power transistors, although quite rugged in most respects, are easily damaged byoverdrive. Be careful not to overdrive the amplifier even momentarily (before applying anydrive signal please check table I for details). Higher-than-rated drive power may destroy thetransistors and VOID ANY WARRANTY.SUPPLY VOLTAGE:The maximum operating voltage is 15VDC. When using the DC power supply make surethat it is not adjusted above 15 volts. If it is possible for the voltage to go above 15 Volts forany reason, including failure of the power supply, install a “crowbar” circuit to prevent damageto the amplifier in the event of excess voltage.CASE TEMPERATURE:High power can mean high temperatures. Mount the amplifier where air can freely circulateover it and where clothing, blankets, etc. will not accidentally be placed over it. Keep dutycycle below limits.TERMINATIONS:The efficiency of this amplifier will degrade if it is operated into anything but a 50 Ù load.Lowered efficiency may mean any or all of the following: lower power output, increasedcurrent drain, higher operating temperature, and reduced life time.FCC CERTIFICATIONTPL Communications commercial amplifiers are FCC certified for the use in Land mobile/fixedservices. The technician installing this amplifier must hold a General Radio Telephone permit and befamiliar with the pertinent FCC rules and regulations.Harmonics, and other spurious, signals from this amplifier are attenuated according to or beyondFCC requirements. For further details consult the appropriate publications.Page 4
INSTALLATIONThe PA1-1AEM amplifier installation is illustrated in figure 2. Mount the amplifier as close to theantenna as practical. Keep coaxial cable runs short, avoiding sharp bends and pinching. Avoid looseconnectors at the ends of the coaxial cables. The antenna should be matched to an SWR better than1.5:1 for best results. Higher SWR will degrade the performance of the amplifier.1. Mount the amplifier away from the sources of heat, and where air can freely circulate around it.Avoid mounting the amplifier in the engine compartment or near the exhaust pipe system.It is also important to securely fasten the unit. An improperly mounted piece of equipment issubjected to damage as it moves about and can cause serious injuries in an accident. Use boltsthrough the holes in the amplifiers flange to fasten the unit to a secure mounting surface (seefigure 2).Figure 2. Amplifier installationPage 52. Wire the DC power connector (Cinch 4 pin female) directly to the battery if possible. Do not usethe present vehicle wiring. Use #10 AWG if possible and certainly no lighter than #12 AWG. Toavoid a possible fire, or other possible damage, make sure a fuse or circuit breaker is installed atthe battery end of the wire. Use the same size as the internal fuse listed in table I.Attach DC input wires in accordance to the diagram in figure 3. If wires are too large for the holes,solder them to the sides of the blades.
INSTALLATION(Continued)Figure 3. DC connector internal wiring3. Connect the antenna to the “RF OUT” terminal with a 50Ù coaxial cable and a PL-259UHF male connector according to figure 4.4. Turn off your radio transceiver. Connect it to the “RF INPUT” terminal with a 50Ù coaxialcable.Figure 4. Antenna connectionPage 6
