ATF63551-11
20 MHz to 6.0 GHz SOI SPDT Switch
The ATF63551-11 is a SOI SPDT switch. The switch may be used in transmit/receive applications by connecting the RF common port (INPUT, pin 5) to either the OUTPUT1 or OUTPUT2 port (pin 1 or 3, respectively) using a low loss path (i.e., a positive voltage applied to either VCTL1 or VCTL2 pins). The switch is “reflective short” on the isolated port.
The switch is manufactured in a compact, 1 x 1 mm, 6-pin QFN package.
