KYOCERA AVX Releases New 3DB Hybrid Couplers
July 4, 2025 | PRNewswireEstimated reading time: 2 minutes
KYOCERA AVX, a leading global manufacturer of advanced electronic components engineered to accelerate technological innovation and build a better future, released a new line of integrated thin film (ITF) hybrid couplers designed to facilitate the continued evolution of high-frequency wireless systems in industrial, automotive, telecommunications, and telemetry applications.
Hybrid couplers are special four-port directional couplers that split input signals into two equal-amplitude 3dB outputs whose phases are shifted by 90°. Many also support performance monitoring and inject signals without interrupting the original signal.
DB0402 couplers enable high-frequency wireless systems in the industrial, automotive, telecom, and telemetry industries.
The new DB0402 3dB 90° hybrid couplers from KYOCERA AVX feature field-proven multilayer thin-film technology engineered to provide excellent high-frequency performance in microwave and RF bands spanning 3,000 to 4,100MHz and enable the quick adjustment of RF parameters. They also feature compact, rugged constructions that measure just 0.040" x 0.023" x 0.014" ±0.002" (L x W x H), enabling board space savings, and lead-free nickel terminations compatible with reflow, wave, vapor phase, and manual soldering techniques, enabling reliable automated assembly. Additional benefits include high power handling (1W continuous), low insertion loss (-0.5dB typical, -0.8dB max.), high isolation, exceptional amplitude and phase balance (0.6dB typical, 1.2dB max. and 2° typical, 5° max., respectively), temperature stability, linearity improvements, low parasitics, high part-to-part and lot-to-lot repeatability, excellent solderability, self-alignment during reflow, and effective heat dissipation.
The series is currently available in four frequency bands with typical performance of 3,200, 3,500, and 3,700, and 3,800MHz and is rated for 50Ω impedance and operating temperatures extending from -40°C to +85°C. It's also compliant with International Automotive Task Force (IATF) and RoHS requirements, manufactured in ISO 9001 facilities, and packaged on tape and reel for automated assembly.
Ideal applications for the series extend throughout the industrial, automotive, telecommunications, and telemetry industries and include base stations, wireless LANs, mobile communications systems, 4G, 5G, and 6G LTE infrastructure, satellite TV receivers, global positioning systems (GPS), RF balanced amplifiers, signal distribution, heavy-duty radios, vehicle location systems, and other high-frequency wireless systems.
"The rapid evolution and expansion of 5G, SATCOM, and other high-frequency wireless technologies is fueling the evolution of enabling technologies, including millimeter wave and MIMO (multiple-input, multiple-output) antennas, which are empowered by innovative microwave and RF components, like our new 3dB, 90° hybrid couplers," said Mohammed Abu-Naim, RF Product Manager, KYOCERA AVX – North America. "Our new hybrid couplers provide customers with space- and cost-saving solutions for maximizing repeatable, high-frequency RF performance in compact and handheld industrial, automotive, telecommunications, and telemetry applications with high power handling and wide operating frequency requirements."

High-frequency EMC Noise in DC Circuits
05/29/2025 | Karen Burnham, EMC UnitedEMC isn’t black magic, but it’s easy to understand why it seems that way. When looking at a schematic like that in Figure 1, it looks like you’re only dealing with DC signals all across the board. There’s a 28 VDC input that goes through an EMI filter, then gets converted to 12 VDC power. Except in extremely rare circumstances involving equipment sensitive to magnetostatic fields, DC electricity will never be part of an EMC problem.
