B41 4-CHANNEL RF REED RELAYS B41 Series Ball Grid Array 4-Channel Relays e BTh 41 contains four independent form A channels in one planar quad package. Cotos Ball Grid Array (BGA) construction offers a breakthrough in reed relay perfor - 1 mance. This patented technology allows for shorter RF paths in a controlled 50 en- vironment 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.
