The MA4P275 has the lowest series resistance for Series Insertion Loss and Shunt Isolation switches. The MA4P789 has the lowest capacitance and offers the highest isolation in Series and Series-Shunt switches through 3 GHz. The MA4P277 and MA4P278 PIN diodes have longer intrinsic layers to produce better distortion performance in attenuators. The MA4P282 and MA4P274 are generalpurpose PIN diodes useful in either switches or attenuators. These parts are available as single diodes, series pairs ( ST ) , reverse series pairs ( STR ) , common cathode pairs ( CK ) , common anode pairs ( CA ) , and unconnected pairs in the featured packages.
