B41 4-Channel RF Relays
Ball Grid Array 4-Channel Relays
The B41 is four independent form A channels in one planar quad
package. Coto’s Ball Grid Array (BGA) construction offers a break-
through in reed relay performance. This patented technology¹ allows
for shorter RF paths in a controlled 50 Ω environment to minimize
signal attentuation. The designer is now able to switch or pass signals
with wider bandwidth and faster rise time than alternative technologies.
This is particularly important in Mixed Signal IC testers. This four-in-
one BGA packaging allows relays to be integrated easily on boards
designed for surface mount processing.
