as you know,load mismath is a big problem in PA design.Valuable materials will be appreciated.

ther are two method for VSWR protection:
1. meaasure it and use a feed back to reduce forward power of PA (Limit reflected power to a known and safe value.)
2. use isolator (circulator+load) at output of the chip, currently low cost high volume drop-in isolators for low power applications and in standard bands are available.
for example see temex catalog.

BEST!
