概要 The 1GG7-8103 (TC750) is a 35 dB by 5 dB step GaAs MMIC step attenuator designed for good input match and low distortion from DC to 12 GHz. It is intended for use as a high-performance solid state step attenuator for RF instrumentation applications.
Each attenuator cell incorpo-rates a "bridged–T" topology with series and shunt MESFET switching elements. Bias to the gate of the FET switches is through a resistor and a diode which improves distortion at low frequencies. Shunt resistors at the input and output ports can be switched on or off to optimize input match. Ground connection is through backside vias.
