RF & Wireless 5G Tester

RF & Wireless 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. ■ Anritsu Corporation www.anritsu.com 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. ■ RFMW, Ltd. info@rfmw.com www.rfmw.com 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

RF & Wireless a given application requirement. The device can cover 2300 to 2700 MHz with a single set of external components with gain: 20.5 dB, OP1dB: 20 dBm, NF: 0.4 dB at 2300 MHz with bias at 5 V and 70 mA. Flexible biasing can accommodate V dd from 2.7 to 5 V and I ddq from 20 to 100 mA. ■ Guerrilla RF, Inc. www.guerrilla-rf.com time of
