1 SP5T SWITCH GaAs MMIC GENERAL DESCRIPTION The NJG1667MD7 is a GaAS SP5T switch featured low insertion loss, high isolation and small size package, and suited for mobile terminal applications. The NJG1667MD7 switches a path between common RF port and five RF ports by three bit control signal from 1.3V of logical high voltage. In addition, this switch includes ESD protection circuits for good ESD tolerance. The NJG1667MD7 is available in a very small, lead-free, halogen-free, 1.6mm x 1.6mm x.397 mm, 14-pin EQFN14-D7 package. PACKAGE OUTLINE NJG1667MD7 APPLICATIONS Multi-mode LTE, UMTS, CDMA and GSM applications Receive system, RX path, and Diversity antenna applications Mobile phone, Tablet PC, Data card, Modem and Router applications FEATURES Low control voltage Low operating voltage Low insertion loss High ESD tolerance Small and thin package Lead -free and halogen-free V =+1.3V min =+2.~+4.5V.4 db P IN =23dBm.5 db P IN =23dBm.6 db P IN =23dBm On-chip ESD protection circuit EQFN14-D7 (package size: 1.6mm x 1.6mm x.397mm typ.)
