• INTRODUCTION:
This document provides a step by step procedure for final assembly and test of a Kaval dual cellular booster. This
procedure presupposes availability of a complete mechanical parts kit and PCBs with all SMD parts installed. Major
activities are installation of PCBs into housing, installation of remaining parts and test. Because of the nature of the
interface connector, it is easier to test PCBs once installed. There are no parts on the underside of the PCB, so all repairs
can be done without removing PCBs from housing. This procedure is specific to the production of cellular band boosters
intended for installation into Cellcom BDA systems. Some adjustment parameters may differ for other customers and
applications. It is recommended that debug and repair not be done by personnel that do test. Unit should be taken to an
offline repair station. Test operator should apply a tag or sticker to defective unit coded with paragraph number of test
step at which unit failed. It is recommended that a test checklist be produced to accompany this document which is used to
record test results for each unit. Checklist should refer to paragraph numbers of tests. This can have plots attached and
should be filed by serial number for future reference.
