BGA relay lets you go with the (re)flow
By Bill Schweber -- EDN, August 19, 2004
Electromechanical relays—the antithesis of ICs—are still vital for many applications, such as automatic test equipment and RF-signal steering. The B41 series from Coto Technology gives you four form-A reed relays in a BGA package, simplifying layout and routing (Picture). These 50Ω, controlled-impedance devices have a 3-dB roll-off 8-GHz frequency, and –40-dB interchannel crosstalk at 1 GHz. Measuring 12×13×4 mm, the four-channel B41 sells for $62.15 (1000).
