  • Description

    The NJG1681MD7 is a GaAs SPDT switch MMIC suitable for LTE/UMTS/CDMA/GSM applications.The NJG1681MD7 features very low insertion loss, high isolation and excellent linearity performance down to 1.8V control voltage at high frequency up to 2.7GHz. In addition, this switch is able to handle high power signals.The NJG1681MD7 has ESD protection devices to achieve excellent ESD performances. No DC Blocking capacitors are required for all RF ports unless DC is biased externally. And the ultra small & ultra thin EQFN14-D7 package is adopted.
