Description

The TriQuint TGS8706-SCC is one of a family of low frequency single-pole double­throw switches. This broadband reflective switch has low power
consumption and can be easily configured for single-pole multi-throw blocks.

The TGS8706-SCC is suitable for all applications that require small size, low insertion
loss, and minimal current consumption, such as EW, phased-array radars, and
telecommunications systems.

Bond pad and backside metallization are gold plated for compatibility with eutectic
alloy attachment methods as well as the thermocompression and thermosonic wire
bonding processes. Ground is provided to the circuit through vias to the backside
metallization.
