SA58643

SA58643 Single-Pole Double-Throw (SPDT) switch Rev. 01 — 20 November 2006 Product data sheet 1. General description The SA58643 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 Ω 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 SA58643 ideal for portable applications. The excellent isolation and low loss makes this a suitable replacement for PIN diodes. The SA58643 is available in an 8-pin TSSOP package. 2.
