IHU RF Levels
The IHU downlink has a high gain to boost weak received signals to levels to drive
the optical components. Do not allow a composite RF level greater than 0 dBm into
the optical transceiver. See the IHU rear RF INPUT MAX information. Uplink power
settings can be done as the RRU instructions.
RRU RF power Considerations
The RRU is available with many RF power outputs. For each product, there are
considerations for pad power dissipation. Product power levels are the Output P1 dB
compression point.
