The following parts are Manufactured in Asia:

Note: These modules are manufactured in ASIA with the sole purpose of reducing costs.

(the soldering of the legs is a manual process and therefore lower cost.

The modules are built to the same design, layout and tested to the same level providing a

finished product with the same RF performance.

There is a difference in the dimension of the legs used. For ASIAN manufacture products the

leg dimensions are 0.25 x 0.4mm.
