RF 开关 IC .1-3.0GHz SPDT GaAs IL .4dB
The is a pHEMT GaAs FET I/C switch. The switch may be used in transmit/receive applications by connecting the RF common port RFC, pin 7 to either the J1 or J2 port pin 1 or 4, respectively using a low loss path i.e., a positive voltage applied to either V1 or V2 pins. The switch is manufactured in a compact, 2 x 2 mm, 8-pin exposed pad plastic Quad Flat No-Lead QFN package..
