4. Functional Description/Truth Table

️· The switch has two control inputs (A & B).
️· The relationship of these inputs and the resulting connection (RFC-RF2, RFC-RF1) is defined in the truth table:
- A = 0, B = 1: RFC connects to RF2 (switch OFF)
- A = 1, B = 0: RFC connects to RF1 (switch ON)

5. Important Notes

️· Blocking Capacitors: Required on all RF ports.
️· Pull-Up Resistors: Can apply control voltage at any RF port using a 10K resistor.
️· Specifications Subject to Change: Always refer to the latest datasheet from MACOM.
