DB0402 3dB 90° hybrid couplers support high-frequency wireless systems with consistent performance and power handling in compact, assembly-friendly designs.
KYOCERA AVX has introduced a new line of integrated thin film (ITF) hybrid couplers designed for use in high-frequency wireless systems across 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.
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.
The series is suitable for use in industrial, automotive, telecommunications, and telemetry applications, including base stations, wireless LANs, mobile communication systems, LTE infrastructure (4G, 5G, 6G), satellite TV receivers, GPS, RF balanced amplifiers, signal distribution, heavy-duty radios, and vehicle location systems, as well as other high-frequency wireless systems.
