Description
The TriQuint TGS8250-SCC is a GaAs single-pole, double-throw (SPDT) FET monolithic switch designed to operate over the DC to 18 GHz frequency range. This switch not only maintains a high isolation loss and a low insertion loss across a wide bandwidth, but also has very low power consumption and attains a rise/fall time of less than 2 ns. These advantages, along with the small size of the chip, make the TGS8250-SCC ideal for use in high-speed radar and communication applications. 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. The TGS8250-SCC is supplied in chip form and is engineered for high-volume automated assembly.
