Kaelus to showcase low PIM combining solutions for GSM, UMTS and LTE

By Telecom Lead Team: Kaelus will be showcasing its new
Range to Fault (RTF) passive intermodulation (PIM) test equipment as well as
new low PIM combining solutions for GSM, UMTS and LTE network deployments.


Range to Fault (RTF) technology uses reflection data
combined with PIM data to identify the location of faults in the RF path. This
technology enables operators to identify and eliminate sources of PIM in their
RF infrastructure and confidently combine multiple bands on the same feed
system without generating harmful interference. Eliminating PIM reduces system
noise allowing higher data throughput and improved service quality.


Kaelus will also be presenting an assortment of RF
filters that combine inputs from multiple base stations at the bottom of the
tower and then separate the bands at the top of the tower for routing to the
appropriate antenna port. Kaelus’ multi-band combiners are low PIM, low
insertion loss and provide high isolation between bands for maximum site
performance.


Kaelus will display a new Tower Mounted Amplifier (TMA)
that simplifies UMTS2100 and LTE1800 network deployments. The TMA2053 is a dual
duplex, AISG controlled TMA that amplifies uplink signal from mobile
subscribers in both the 1800 MHz and 2100 MHz bands while allowing downlink
signals to pass through with very low insertion loss. In combination with a
DBC0021 dual band combiner, this TMA enables 1800 and 2100 MHz systems to
co-exist on the same feed system and to utilize the same wideband antenna.
