(note 1)
Note 1: The switch must operate with gated bias voltage input at 1% to 99% duty cycle.
Note 2: No external matching components.
Note 3: Values to be agreed to upon characterization data review.
Note 4: The FEM can be placed in transmit/receive WiFi and Bluetooth modes simultaneously with increased insertion loss.
