• Option 08: Pre-amplifier
Outline When Pre-amplifier is On, the following performance is specified for the Main Unit specifications. (For the MS8608A,
these are applied on Low Power Input.)
Gain 20 dB typical
Noise figure 6.5 dB typical (Input frequency
≤
2 GHz),
12 dB typical (Input frequency > 2 GHz)
Frequency range 100 kHz to 3 GHz
Frequency band composition Band 0: 100 kHz to 3.0 GHz, Band 1–: 3.15 to 6.3 GHz, Band 1+: 6.2 to 7.8 GHz, Band 2+: 7.7 to 13.2 GHz
(MS8609A only)
Pre-amplifier can be used only for Band 0.
