Coto Technology disclosed that it has released the first four independent channel, form-A, planar BGA reed relay. Target applications include mixed-signal and IC testers where high package density and excellent RF performance are important.

Unlike the company's B10, B40 and other high-performance RF reed relay products, the B41 series requires no slot or hole in the PCB to mount the device - a feature which simplifies the design of multi-layer boards.

Coto's new, patented technology also allows for shorter RF paths in a controlled 50-ohm environment to minimize signal attenuation. Each channel has an RF insertion loss (-3dB roll-off point) of >8GHz, and a combination of coaxial and magnetic shielding reduces adjacent closed inter-channel RF crosstalk to -40dB at 1GHz, with test signal and magnetic interaction between channels reduced to <16 percent.

The BGA packaging, with JEDEC standard dimensions, allows the newly-released device to be easily installed on PCB designed for surface-mount processing using either manual or automated pick-and-place techniques. In 1,000-unit quantities, the B41 is priced at $62.15 ($15/channel) and delivery is stock to 6 weeks.
