Local oscillator input frequency twice or four times the required operating frequency.
Output power reduced dB for dB with forward path attenuation.
Peak power: PEP measured with 2-tone signal (two equal amplitude tones).
Measured between noise floor and mean power in a two-tone modulated wanted signal.
Measured at 400MHz, 5MHz offset over specified Forward Path Output Power range and with
forward path attenuation between 0dB and –5dB. NB: typical noise performance achieved at
typical output power and above.
Measured at 400MHz, 5MHz offset with specified Forward Path Output Power for relevant
attenuation level.
