Lower Both Uplink and Downlink

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.
