Page 53 KYOCERA AVX Releases Hybrid Couplers


FOUNTAIN INN, SC — KYOCERA AVX has 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 applica- tions.


Hybrid couplers are special four-port


directional couplers that split input signals into two equal-amplitude 3 dB 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 cou-


plers from KYOCERA AVX feature field- proven multilayer thin-film technology engi- neered to provide excellent high-frequency performance in microwave and RF bands spanning 3,000 to 4,100 MHz and enable the quick adjustment of RF parameters. They also feature compact, rugged constructions, enabling board space savings, and lead- free nickel terminations compati- ble with reflow, wave, vapor phase, and manual soldering techniques, enabling reliable


Gold-Plated vs. Silver Contacts

age environments where elec- trical loads are substantial and cost-efficiency matters, silver contacts are typically the right choice — especially when oxida- tion can be mitigated by the current itself. However, in low- voltage or signal-sensitive applications, or in environ- ments with high humidity or contaminants, gold-plated con- tacts (or the even more robust silver/gold alloy contacts) deliv- er the performance and stabili- ty required. Use gold-plated contacts low-current


for low-voltage,


applications that demand long- term reliability and resistance to oxidation, especially in pol- luted or humid environments. Use silver/gold alloy con-


tacts in high-value applications where longevity and dual-volt- age switching (both low and high) are required. Use silver contacts where


the application involves higher currents and voltages and where cost efficiency is critical — provided the switch can self- clean through electrical load. By selecting the appropri-


ate contact material for each use case, engineers and design- ers can improve the perform- ance and durability of their HMI solutions while balancing long-term cost and reliability. Contact: EAO Corp.,

automated assembly. Additional benefits include high power handling, low insertion loss, high isolation,


exceptional amplitude and phase balance, temperature stability, linearity improve- ments, low parasitics, high part-to-part and lot-to-lot repeatability, excellent solderabili- ty, self-alignment during reflow, and effec- tive heat dissipation. The series is currently available in four


frequency bands with typical performance of 3,200, 3,500, and 3,700, and 3,800 MHz and is rated for 50W impedance and operating temperatures extending from –40 to +185°F (–40 to +85°C). Contact: KYOCERA AVX, One AVX
