tors on RF ports and 100 pF bypassing on pins 4 and 6.  
Description  
The SW-438 is a GaAs MMIC SPDT switch in a low cost  
SOT-363 surface mount plastic package. Typical applica-  
tions include transmit/receive switching for Bluetooth and  
WLAN equipment. The SW-438 can also be used in applica-  
tions up to 500 mW in systems such as cellular, PCS,  
DCS1800, GSM, CDMA and other analog and digital wire-  
less communications systems.

M/A-COM fabricates the SW-438 using a 0.5 micron gate  
length GaAs p-HEMT process. The process features full pas-  
sivation for increased performance and reliability.

RF Common Port  
Please note the values of the external capacitors. The ca-  
pacitors at each of the RF ports are used as for achieving  
optimum insertion loss. They also provide DC blocking for  
positive control. The 8 pF (0402) capacitor is recom-  
mended for 2 - 3 GHz operation. If this value is changed or  
the capacitor placed too far from the switch, the perform-  
ance will be affected. We also recommend 100 pF bypass  
capacitors on pins 4 and 6.

Ordering Information  
For broadband applications with positive control voltages,  
use DC blocking capacitors with value of 39 pF or more.

1. External DC blocking capacitors are required on all RF ports.  
2. If negative control is used, DC blocking capacitors are not required on RF ports.
