RFMW announces design and sales support for a 5G ready antenna from Cirocomm Corporation. The EHA8A102 Hexaband antenna is designed for remote control applications via cellular services including fleet management and asset tracking as well as remote monitoring and control such as robotics and high performance drones. The embedded design provides wideband performance in traditional LTE bands between 700 MHz and 2.1 GHz, but extends through the 3.5 GHz 5G band and into 5 GHz WiFi bands (5 to 6 GHz). At just 120 x 30 mm, the hexaband antenna offers efficiency in excess of 50% in all bands…

RFMW announces design and sales support for test accessory kits from Rosenberger North America. Designed for mmWave 5G testing applications, two kits offer adapter and cable assembly options along with a calibrated torque wrench. The set is supplied in a sturdy, wooden box to organize and protect the contents. The 5GKT-09-000 kit contains 2.4 mm components for system testing to 50 GHz while the 5GKT-08-000 kit contains 1.85 mm components for system testing to 70 GHz. Ideal for laboratory or field use, both kits can be upgraded to add low loss, phase stable cable assemblies, terminations and attenuators.

RFMW announces availability of a portfolio of field replaceable SMA connectors. The San-tron portfolio is comprised of field replaceable connectors capable of accepting 0.012”, 0.015”, and 0.020” diameter launch pins with 1/2” square, 3/8” square, 1/2” by 3/8”, .500” 2-hole, .550” 2-hole or .625” 2-hole flange configurations. The connectors offer low VSWR of <1.10:1 from DC to 18.0 GHz and <1.15:1 from 18.0 to 27.0 GHz. They feature high-performance gold-plated beryllium copper contacts, polyetherimide (PEI) capture bead, polytetrafluoroethylene (PTFE) insulators and rugged stainless-steel bodies. San-tron field replaceable SMA connectors fully comply with MIL-STD-348.
RFMW announces design and sales support for high-gain, high-efficiency transistors. NXP’s MRF24G300HSR5 RF power GaN on SiC transistor provides 330 Watts of CW power from 2400 to 2500 MHz for ISM band, RF Energy applications. It’s the first solid state device to exceed the efficiency of magnetrons for industrial heating applications, welding and drying. Other potential uses include medical diathermy and microwave ablation. Operating from a 48V supply, the MRF24G300HSR5 has a pre-matched RF input and boasts 73% efficiency and >15 dB of gain. The higher power density of GaN on SiC enables a high output impedance, making…
RFMW announces design and sales support for a half-duplex, transmit/receive integrated circuit. The Renesas F5280 IC is a 4-channel, TRX, half-duplex silicon device using a SiGe BiCMOS process for 28 GHz 5G phased-array applications. The core IC has flexible gain and phase control on each channel to achieve fine beam steering and gain compensation between radiating channels. Designed for 25 to 31GHz operation with fast-beam switching and fast beam-state loading, typical Tx/Rx switching time is 100 ns. Typical gain and phase settling time is 20 ns. The device contains programmable on-chip memory and boasts 3° typical RMS phase…
Adapters are the interfaces between two dissimilar components. While an adapter’s performance is directly proportional to its application and how stringent the requirements, it should have a minimal effect on the fidelity of the signal passing through it and not introduce any new unwanted signal phenomenon. For example, the user should not see an excessive signal power loss over frequency or over-moding (where a signal loss in a small frequency bandwidth results in an insertion loss dip). When choosing an adapter for measurements, users are presented with options or grades of performance. Common grades include calibration, instrumentation, general purpose,…
RFMW announces design and sales support for a high performance power amplifier. The Qorvo QPA2610, GaN on SiC amplifier provides 2 W of saturated output power with 23 dB large signal gain from 8.5 to 10.5 GHz. With 47% power-added efficiency at 20 V drain bias, RF ports are matched to 50 Ω and include integrated DC blocking capacitors. The QPA2610 is ideally suited for phased array radar applications where tight lattice spacing is required. Offered in a 5 x 5 mm plastic overmold QFN package.
RFMW announces design and sales support for Knowles – Novacap SV Series capacitor assemblies. SV series capacitors offer high capacitance-to-volume ratio, low equivalent series resistance (ESR) and low equivalent series inductance (ESL) while reducing overall circuit board footprint. Vertical stacking of ceramic capacitors provides far superior performance than either aluminum or tantalum electrolytic capacitors. Up to ten, same size chips, may be stacked with various lead configurations to safeguard against thermal and mechanical stresses as with the SV2220BB476M101LNW-10R, 47uF 100V (VDCW) assembly. 100% tested for dielectric withstanding voltage, insulation resistance, capacitance, and dissipation factor, the capacitors are suited for…
