NJG1657MD7 DPDT SWITCH GaAs MMIC ! GENERAL DESCRIPTION The NJG1657MD7 is a GaAs DPDT switch featured low insertion loss, high isolation and small size package, and suited for mobile terminal applications. The NJG1657MD7 switches a path between common RF port and five RF ports by three bit control signal from 1.7V of logical high voltage. In addition, this switch includes ESD protection circuits for good ESD tolerance. The NJG1657MD7 is available in a very small, lead-free, halogen-free, 1.6mm x 1.6mm x 0.397 mm, 14-pin EQFN14-D7 package. !
