5G Tester contributes
to verify the advanced
Technologies of 5G
Modem
Anritsu announced MediaTek‘s Helio
M70 5G modem has achieved the maximum
downlink and uplink throughput
using Anritsu’s Radio Communication
Test Station MT8000A, providing a flexible
test platform for ultrafast, largecapacity
5G communications using
wideband signal processing and beamforming.
With its cutting-edge NSA and
SA modes, the all-in-one MT8000A
supports sub-6 GHz and mmWave RF
tests as well as protocol tests for development
of advanced 5G technologies,
such as 4x4 MIMO, to increase data
speeds in the sub 6 GHz band.
MediaTek announces the Helio M70 is
the only 5G modem with both LTE and
5G dual connectivity (EN-DC), supporting
every cellular generation from 2G
to 5G. Designed for 3GPP Release 15
compliance and supporting initial nonstandalone
(NSA) and future standalone
(SA) 5G network architectures, the
Helio M70 can connect to 5G NR and
4G LTE bands worldwide while supporting
High Power User Equipment
(HPUE) and other key carrier features.
MediaTek’s Helio M70 is among the
industry’s first wave of 5G multi-mode
integrated baseband chipsets. With its
multi-mode solution, the Helio M70
simplifies the design of 5G devices
with a comprehensive power management
plan, enabling companies to
design mobile devices with a smaller
form factor, improved energy efficiency
and sleek appearance. The Helio
M70 baseband chipset is available now,
and is expected to ship in the second
half of 2019.

Universal Differential Fanout
Buffer
RFMW, Ltd. announced design and sales
support for a fully integrated signal fanout
buffer from Integrated Device Technology,
Inc. (IDT). The 8T79S308 is designed for
distribution and fanout of high-frequency
clocks or low-frequency synchronization
signals in either baseband or RF sections of
wireless infrastructure radios. The 8T79S308
is optimized to deliver very low phase noise
clocks and precise, low-skew outputs, low
device-to-device skew characteristics and
fast output rise/fall times which help the
system design achieve deterministic clock
phase relationship across devices. Featuring
a low phase noise floor of -160 dBc/
Hz (156.256 MHz clock), flexible input
selection offers 1:8 fanout modes or dual
1:4 buffer fanout modes. The supported
clock frequency range is 0 to 3 GHz and
various core and output supply voltages
are accommodated. Available in a 6 x 6 mm
SMT package.

Energy Efficient FEM
RFMW, Ltd. announces design and sales
support for a 2.4 GHz front end module
(FEM). The Qorvo QPF4228 integrates a 2.4
GHz power amplifier (PA), regulator, single
pole three throw switch (SP3T), low noise
amplifier (LNA), coupler and power detector
with optional DC voltage or RF signal output.
Designed for 802.11n-ax access points
and wireless routers, the QPF4228 offers 33
dB of Tx gain and 15 dB of Rx gain with
LNA noise figure of 2.2 dB. Energy efficient,
the module boasts 13 dBm power output at
-47 dB DEVM with a power dissipation of
