RF-DC and RF-RF crossovers

20 February 2013 Interconnection

AVX has introduced two new series of miniature RF-DC and RF-RF SMT crossovers capable of supporting frequencies up to 6 GHz. Ideal for base stations, mobile communications, GPS, vehicle location systems and wireless LANs, the X2A and X2B series provide designers with an alternative to PCB vias and coaxial jumper cables.

Utilising AVX’s patented MLO technology, which matches the CTE of PCB material and provides low loss across a wide RF spectrum, the new parts provide low-cost and very low-profile solutions for applications in which a critical RF circuit trace intersects a DC or an RF circuit.

The crossovers are designed for use in temperatures ranging from -55°C to +85°C, and feature low-loss, DC/high-isolation and NiSn terminations compatible with automatic soldering technologies.

Both series are packaged as 2020 case size land grid arrays which feature a low profile, improved heat dissipation, excellent solderability, and a CTE that matches most common circuit board materials. They are subjected to JEDEC reliability standards and have been 100% tested for electrical parameters and visual characteristics.
