Question

What kind of RF-switch is recommended for the replacement of the uPG2164 DPDT RF-switch used in most of reference designs?

Answer

The RF-switches listed below can be good alternatives to replace the uPG2164 DPDT RF-switch. These switches have approximately the same specifications/characteristics/ratings and footprint as the uPG2164.

 

Example list of RF switches for the replacement:

-SKY13355: http://www.skyworksinc.com/Product/809/SKY13355-374LF?IsProduct=true

-SKY13381: http://www.skyworksinc.com/Product/847/SKY13381-374LF?IsProduct=true

-SKY13411: http://www.skyworksinc.com/Product/1486/SKY13411-374LF?IsProduct=true

-SKY13438: http://www.skyworksinc.com/Product/1704/SKY13438-374LF?IsProduct=true

-CKRF2164

-CG2164

 

The RF switch used in the designs needs to have:
- low insertion loss
- high enough frequency capability
- high isolation

- high enough power capability

- low harmonic re-generation, i.e. low distortion

- small size
etc.
