hd33 PS Remote Radio Unit
The hd33 PS is a dual-band or quad band remote radio unit (RRU) that provides 2 W or 5 W
of output power depending on the number of bands.
The dual-band unit supports one or two bands in a sealed type 1 pluggable module chassis.
The quad-band unit supports up to four bands in a type 2 sealed chassis with door.

On the downlink path, the hd33 PS remote receives an aggregated stream of digitized RF
signals from an hdHost PS or airHost PS, which it then converts into analog RF signals.
Depending on the frequency band, the signal is either amplified in the RF module and then
sent out through simplex RF ports to an external filter, or sent to an internal multiplexer and
then out through N-type antenna ports.
On the UL path the hd33 PS remote receives analog RF signals for the RF band, either from
an external VHF/UHF filter or directly from the antenna network. The RF signals are
converted into a digital data stream and then delivered over optical fiber to an hdHost PS or
airHost PS.
The hd33 PS remote also accommodates a 1 Gbps Ethernet backhaul for transporting the
data from nearby IP devices such as security cameras and Wi-Fi access points.
