Notes
1.
Output power at 6V measured with maximum Input power for Rated Output CW Power.
2.
All Intermodulation (IMD) specifications are quoted for a two-tone test. The tones are of equal amplitude with 600Hz frequency
spacing. The amplitude of each tone is 6dB below the rated PEP to give a composite output power of 5.5W PEP. The level of IMD
is measured in dBc relative to one of the two fundamental tones at the output of the power module.
3. The power delivered by the power amplifier module is controlled by varying the input drive level. The output power is continuously
variable over the quoted power range, i.e. the rated output power to the specified minimum power.
