Application Circuit

Notes:

1.

This switch can be configured as a Single Pole, Single Throw (SPST) by terminating one unused RF switched port with a 50

Ohm load.

2.

VC can be biased from either pin 1 or 6 and the non-biased pin can be left open.

3.

VC_N can be biased from either pin 5 or 18 and the non-biased pin can be left open.

4.

External components are not required

Bias Up Procedure

1. VC or VC_N set to 0 V (see Function Table for RF Path)

2. VC_N or VC set to -28 V (see Function Table for RF Path)

3. Apply RF signal to RF Input

Bias Up Down

1. Turn off RF supply

2. Turn VC_N or VC to 0 V

3. Turn VC or VC_N to 0 V
