Four PIN Diodes in one package reduce design parasitics and improve circuit density. PIN Configuration PIN Function RF In Series Bias RF Out PIN 4 5 Function Shunt 1 Bias Shunt 2 Bias 1 2 3 Applications These PIN Diode Attenuators perform well where RF Signal Amplitude Control is required in 50 Ω Handset Circuits and 75 Ω Broadband CATV Systems. Exceptional Insertion Loss, Attenuation Range, and IP3 at <10 mA bias make these devices suitable for better power level control in RF Amplifiers.
