RF power is measured by connecting a 50 ohm, re- sistive wattmeter to the RF output connector. With a nominal battery voltage of 7.2V, and the transmitter properly adjusted the RF output measures: POWER HIGH INPUT POWER: (7.2V)(1.80A) = 12.98 Watts OUTPUT POWER: 4.2 Watts Efficiency: 32% LOW POWER INPUT POWER: (7.2V)(1.20A) = 8.64 Watts OUTPUT POWER: 2.1Watts Efficiency: 24% 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 #9. 2.987(a) AUDIO LOW PASS FILTER The audio low pass filter is included and the plot is shown as EXHIBIT #13.
