Product Description

The BSW6421 is a reflective SPDT RF switch that can

be used in high power and good performance WiMAX

802.16, WLAN 802.11 a/b/g/n/ac/ax and DOCSIS

3.0/3.1 applications.

This device is packaged in RoHS-compliant with

1.5x1.5mm, 6-lead UDFN package. It must be used

with back side ground soldering.

The BSW6421 has robust ESD protection circuits at all

pins and temperature performance (operating tem-

perature range : -40 ~ +105°C), furthermore this

switch does not require blocking capacitors.

This device also has a high linearity performance over

all temperature range such as IIP3, IIP2.

A functional block diagram is shown in Figure 1.
