RFMW announces design and sales support for a Commercial Off The Shelf (COTS) mixer from Qorvo. The QPX0003D, 30 to 40 GHz I/Q Mixer can be configured as an image reject mixer, a single sideband upconverter, or a QPSK modulator/demodulator. Provided as DIE, the device utilizes two double balanced mixer cells and a 90⁰ hybrid on the LO port. An external 90⁰ hybrid on the IF port is required to complete the image rejection or sideband suppression. The QPX0003D is a much smaller alternative to higher cost hybrid I/Q mixers and single sideband upconverter assemblies. LO/RF isolation is > 30…

RFMW announces design and sales support for Ultra-wideband (UWB) antennas from Sangshin Elecom. The KSCA-UWBS86A linear polarized, UWB chip antenna is designed to offer high efficiency in channels 1 through 7 (3,200 to 7,200 MHz) making it ideal for end-use products targeting markets in the United States, Europe and parts of Asia. With a small form factor of only 8 x 6 mm, the device achieves 6 dB of gain in channel 4 (4,000 MHz) while covering a wide range of the most common UWB channels. The KSCA-UWBS54A is a complementary solution operating across channels 5 to 8 (6 to…
RFMW announces design and sales support for a low profile, multi-band massive IoT front-end module from Skyworks. The SKY68031-11 is the world’s smallest, multi-band RF front-end (RFFE) module for licensed, low-power, wide-area network (LTE-M/NB-IoT) applications including asset tracking, health and fitness wearables, smart metering and industrial monitoring. This module integrates the entire RF front end necessary for a cellular IoT radio operating in low-band (5, 8, 12, 13, 14, 17, 18, 19, 20, 26, 28, 85) and mid-band (1, 2, 3, 4, 25, 39, 66, 70) frequencies. The FEM monolithically integrates a broadband power amplifier, transmit harmonic filters, antenna switch…
As 5G network applications continue to gain momentum, compatible radio frequency (RF) connector systems are playing an increasingly crucial role. Factors like higher signal frequencies and data rates, packing density and signal integrity requirements, are accelerating the demand for high-performance and high-quality board-to-board connection solutions. Rosenberger, a global and innovative leader in RF technology, has developed a wide range of RF interconnects for future PCB applications. These board-to- board solutions connect circuit boards on top of each other or in parallel. The use of connectors in these mobile electronic devices presents two challenges: The compensation of manufacturing tolerances PCB movement…
RFMW announces design and sales support for a high performance filter from Qorvo. The QPQ4900 is a compact, bulk-acoustic wave (BAW) band pass filter with 4920 MHz center frequency and 160 MHz bandwidth for Sub-Band n79 applications in TDD small cell base stations, base station infrastructure, repeaters and boosters. The QPQ4900 insertion loss is 1.4 to 1.9 dB (typical) with high out-of-band attenuation of WiFi signals. Offered in a 2.0 x 1.6 mm package.
RFMW announces design and sales support for a unique antenna from Unictron (formerly SANAV). The Unictron MT4B-AC-BL03 is a 2-in-1 LTE/GNSS combination featuring a single LTE antenna covering 698 to 2690 MHz and an active GNSS antenna covering GPS, BEIDOU and GLONASS L1 bands. The GNSS antenna offers 27 dB peak gain and out of band suppression up to 55 dB. The MT4B-AC-BL03 is screw mounted with base launch cables and is IP67 rated for external use. It is fitted with 2 x 5 meter cables and SMA Male connectors, making it ideal for fleet management and telematics applications. Customer…
RFMW announces availability of discrete devices from Microwave Technology (MwT). The MwT-7F GaAs MESFET delivers 21 dBm P1dB at 12 GHz and is ideally suited to applications requiring high-gain and medium linear power in the 500 MHz to 26 GHz frequency range. Small signal gain is 15 dB. Offered in a 365 x 250 micron chip, the MwT-7F can be used in military and hi-rel SWaP designs and is also available in multiple packaged configurations, all with MTBF values better than 1×108 hours at 150 C channel temperature.
RFMW announces availability of a white paper from Ampleon – “ART (Advanced Rugged Technology)”. The paper describes Ampleon’s advancements with ruggedized Si LDMOS transistors of up to 2 kW of RF Power for 1 through 400 MHz applications. ART technology was engineered to obtain a high drain-source breakdown while maintaining a compelling low output capacitance to allow for a rugged transistor with high transconductance in frequency ranges from HF through UHF. The white paper includes product details and reference design information.
RFMW announces design and sales support for an unmatched, single-stage amplifier from Qorvo. The QPD0005M GaN power transistor supports driver amplifier applications for massive MIMO Doherty configurations from 2.5 to 5 GHz. A 6 Watt Psat device, it provides 18.6 dB of P3dB gain with 74% power added efficiency in a 48 V system. The QPD0005M is available in a small, 4.5 x 4 mm DFN package.
RFMW announces design and sales support for a Southwest Antennas’ monopole whip antenna. The 1000-046 omni-directional antenna operates from 330 to 360 MHz with a peak gain of 2.0 dBi. This flexible antenna features a tough, braided aircraft wire element with a sealed heat shrink exterior and fully potted and waterproof base containing the antenna’s matching components. The resulting antenna is rugged for use in harsh environments yet is flexible enough to bend if the whip is impacted by another object. The 1000-046 features a BNC male connector for attachment.
