Control & Bias Voltages
Truth Table
Application Circuit
DC blocking capacitors C1 & C2 are required on RF1 & RF2. Choose C1 = C2 = 100 ~ 300 pF to allow lowest customer specific
frequency to pass with minimal loss. R1 = 5K Ohm is required to supply voltage to the circuit throught either PIN 5 or PIN 8.
