Rohde & Schwarz Transmitters
- from DAB to 5G and Beyond
Manfred Reitmeier, Vice President of Broadcast and
Amplifier Systems at Rohde & Schwarz, considers the future
of digital 5G broadcasting and the potential of
multicasting systems...

N

ormally, this month would
be dominated by events in
Amsterdam. IBC is very important to
Rohde & Schwarz, since it provides
us with opportunities to meet and
spend time with our highly valued
customers. This year, IBC is cancelled
for very sound and sensible reasons,
however both life and business go on.
The transmitter and satellite amplifier
businesses are cornerstones of Rohde
& Schwarz's operations. So, in the
absence of our IBC exhibit, let's look
a little closer at some of the news we
would have brought to IBC.
Firstly transmitters. At IBC, we
would have showcased our latest
developments in DAB transmitters.
This includes a new low power DAB
radio transmitter - the TLV9. This is an
important addition since it completes
our transmitter portfolio in this
category. Rohde & Schwarz has built
a strong market leadership position
in UHF and VHF both TV and Radio
transmitters and we continue to build
on this position in the future.
In this market area, we had a highly
successful business drive in North
America, responding to the country's
REPACK initiative. To date, we have
supplied and installed in excess of 500
transmitters to our customer base in
the U.S.
"Rohde & Schwarz has built
a strong market leadership
position in UHF and VHF both
TV and Radio transmitters"

Following on the heels of this is
NEXT Gen TV, also known as ATSC
3.0, where we are working with many
broadcasters. We are in the fortunate
position that we were able to make
our recently sold transmitters ATSC 3.0
ready, so to implement Next Gen TV,
our customers only need a softwarebased upgrade instead of exchanging
the exciters or even wholesale
infrastructure replacement.
And in other news, we are proud
to announce a major FM radio
transmitter contract in Australia. We
have supplied 200+ liquid-cooled FM
transmitters. In a country where many
remote communities rely on radio
for news and entertainment, this is a
strategically important and large-scale
project.
Solid state satellite amplifiers
- a new and radically different
approach proves popular
Using
the
latest
transistor
technology, Rohde & Schwarz has
recently introduced a new family of
solid-state amplifiers which combine
the best of both worlds and offer
users new and radically different
functionality compared with traditional
tube-based amplifiers.
Importantly, if transistors fail during
operation, the amplifier continues to

operate with reduced output power.
With no high voltages used within
the product it is easy to maintain
and it offers a significantly longer
operating lifetime than its tube-based
counterpart.
We have developed two power
classes for our uplink amplifiers:
400W and 750W models are available
as indoor and outdoor units and for
the two frequency bands 12,75 GHz
to 13,25 GHz and 13,75 GHz to 14,5
GHz. The amplifiers can be used in
large scale fixed satellite installations
serving customer applications such
as broadcasters, telecom & internet
service providers, global business
institutions, government and nongovernment organizations. At the
same time, the smaller amplifier
can also be used for mobile, vehiclemounted satellite applications.
A completely new application for our
latest innovation in this microwave
frequency range is the field of Medical
Healthcare where the RF signal from
our solid-state amplifier is used
for non-invasive tumour disease
treatments.
Now, we can announce that we
have started global shipments of the
PKU100 family of solid-state satellite
amplifiers. Already, we are working
with a major Scandinavian Teleport
operator. Here, the PKU100750 will be used to replace
the existing Travelling Wave
Tube Amplifiers, which allows
the network operator to
simplify and optimize their
satellite uplink setup when
using our new technology.
We have successfully carried
out a proof of concept
trial, where the customer
identified our smart signal
adaptive
linearization
capabilities being a deal
maker, especially in the
mountainous regions where
signal strength can suffer as a
result of the topography and
changing weather conditions.

Next Gen TV powered by ATSC 3.0

5G Broadcast - a new dawn
for billions of mobile
consumers worldwide
At Rohde & Schwarz, we have
introduced the world's first complete
5G Broadcast solution, which consists
of the core network functionality
provided by the new BSCC broadcast
service and control center and R&S Tx9
transmitters, which support FeMBMS.
This all-in-one solution covers all
roles within a 5G Broadcast/Multicast
workflow from the content provider to
the consumer, is fully compliant with
3GPP Release 14 and has the upcoming
3GPP Release 16 in focus as well. It
enables broadcasters to contribute
their valuable assets for efficient
distribution of high-quality video to the
future 5G ecosystem.
Running as part of the core network,
the BSCC broadcast service and control
centre is a software defined solution
that delivers multimedia content over
LTE/5G networks in broadcast mode.
It generates service announcements
and encapsulates multimedia content
into specific FeMBMS bearers to be
delivered from the evolved packet
core (EPC) down to the receiver. At IBC
we would have presented our latest
software release 2.0 for BSCC with
major feature enhancements for the
network.
The BSCC 2.0 enables content
providers to deliver high data
rate content to their mobile users
simultaneously with consistent quality
of service. This results in higher quality
of experience, spectral efficiency and
reduced costs.
