ELECTRICA AL CONNEC CTIONS Warning – Op perating withou ut antenna or dummy d load (50 0ohm) can permanently damage to the RF p power transistor. Warning – Ch heck the outputt connection before applying g DC voltage to o the module.
WARNING - NC connecctions are forr lab tests on nly not for cos stumer use, using those pins can dam mage the amplifier!
M HARDWARE E MODULE MOUNTING/H Warning - If th he module will be over heated d above 50°C – Air fan should be applied to o the heat sink. Warning – Ov verheating can cause perman nently damage to the power transistor.
