CONNECTIONS
2.5.8 RX IN and RX OUT
RX IN connector is the direct input, bypassing Band Pass Filters (BPFs).
RX IN connector may be used for connection of the receiving antennas, transverters, additional
BPFs, preamplifiers, attenuators etc.
Note:
( The signal from RX IN connector goes to the ADC input and may be amplified by the
preamplifier +10dB, if it will be chosen in the software.
Warning!
i Maximum allowed signal level on the RX IN connector is 0.3V of the active
voltage (RMS). Do not exceed it, it may result in the transceivers overload and
ADC fatal damage.
RX OUT connector is the output of the transceivers receive path. The signal transferred to the
transceivers HF path via active antenna input, goes to the RX OUT, when the RX IN is chosen.
Between RX OUT and RX IN connectors may be added additional filter or box of filters,
preamplifier, attenuator, signal divider etc.
Note:
( The signal passing through the transceivers HF path could be affected by the attenuator -
20dB, if it will be chosen in the software.
