RF power is measured by connecting a 50 ohm, re- sistive wattmeter to the RF output connector. With a nominal battery voltage of 7.5 VDC, and the transmitter properly adjusted the RF output measures: POWER HIGH INPUT POWER: (7.5V)(1.8A) = 13.5 Watts OUTPUT POWER: 4.8 Watts Efficiency: 35% POWER LOW INPUT POWER: (7.5V)(0.9A) = 6.75 Watts OUTPUT POWER: 2.0 Watts Efficiency: 29.6% METHOD OF MEASURING RF POWER OUTPUT /-----------\ /---------\ |Transmitter|---------------------|50 ohm | |under test | |Resistive| \-----------/ |Wattmeter| | \---------/ /-----------\ |Power | |Supply | \-----------/ 2.987(a) VOICE MODULATION CHARACTERISTICS: (a) AUDIO FREQUENCY RESPONSE See the EXHIBIT #12. 2.987(a) AUDIO LOW PASS FILTER The audio low pass filter is included and the plot is shown as EXHIBIT #14.
