Table 7.
(Input at FMIFAMP1IN, fc = 10.7MHz, no mod)
(Output at FMIFAMP1OUT loaded with 330Ω)
(antenna level = FMIFAMP1IN – 31dB)
Table 8.
(Input at FMIFAMP2IN, fc = 10.7MHz, no mod)
(Output at FMIFAMP2OUT loaded with 330Ω)
(antenna level = FMIFAMP2IN – 45dB)
Gain MUST BE SET to 14dB for ISS operation.
