SA630
Single-Pole Double-Throw (SPDT) switch
Rev. 3 â 23 July 2014
Product data sheet
1. General description
The SA630 is a wideband RF switch fabricated in BiCMOS technology and incorporating
on-chip CMOS/TTL compatible drivers. Its primary function is to switch signals in the
frequency range DC to 1 GHz from one 50 ï channel to another. The switch is activated
by a CMOS/TTL compatible signal applied to the enable channel 1 pin (ENCH1).
The extremely low current consumption makes the SA630 ideal for portable applications.
The excellent isolation and low loss makes this device a suitable replacement for PIN
diodes.
The SA630 is available in an 8-pin SO (surface-mounted miniature) package.
