The TriQuint TGL8784-SCC is a monolithic variable attenuator which operates from 2 to 20 GHz. This analog attenuator can operate from a single +2.5 volt power supply if used with an external variable voltage divider circuit. Typical RF performance at 10 GHz includes an insertion loss of 2 dB, maximum attenuation of 15 dB at 10 GHz and input/output return loss of greater than 10 dB. The device is an absorptive attenuator designed using MESFET technology employing a "PI" configuration which reduces bias currents and simplifies bias networks. The broadband capabilities of this device are versatile in many applications such as telecommunications, military and space. This device has a space heritage. DC blocking capacitors are provided on-chip. Bond pad and backside metallization is gold plated for compatibility with eutectic attachment methods as well as thermocompression and thermosonic wire bonding processes. The TGL8784-SCC is supplied in chip form and is readily assembled using automated equipment. Ground is provided to the circuitry through vias the backside metallization.
