Power Up/Down and Operational Controls

Scenario 1

Sequence for power up and power down from the phone battery or supply that is connected to

RFSW1012 VBATT Pin.

Power Up

Turn on VBATT (supply), then EN, then CTRL. Then (20mS or greater), apply RF signal

Power Down

Turn off RF signal, then CTRL, then EN, turn off VBATT (supply)

Scenario 2

Sequence for going in and out of a shutdown mode, keeping the VBATT or supply on,

but disabling

/enabling the RFSW1012 by the EN pin

Power Up

Turn on EN (enable), then CTRL, then (5mS or greater), turn on RF Signal

Power Down

Turn off RF signal, then CTRL, then EN (disable)

Scenario 3

When changing switch positions between RF1 and RF2, no RF signal should be applied to any RF

port while the CTRL is changing states

Switching Ports

Turn off RF signal, then change CTRL state, then wait (5mS or greater), then turn on RF signal
