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. • EQUIPMENT The following tools or instruments are required for final assembly: Multimeter Booster test interface (custom made) 24V DC Power supply with current limiting at 1A Scalar Network Analyzer capable of 900 MHz operation 1W minimum 10 or 20 dB attenuator, type N.

This procedure applies to amplifiers to be used together with external electronic fault monitoring modules in Kaval BDA systems. Certain internal fault detection features are not aligned in such case and these adjustments are set to positions which defeat these functions. Alignment of fault detection circuitry not necessary in BDA applications are covered in another document. The Kaval 20W power amplifier is a single stage Class AB linear power amplifier using a high power LDMOS amplifier transistor. Compression point is about 20W, and intermod performance rivals that of similar amplifiers with 30W ratings. This design is optimized for best intermodulation and minimum heat in multicarrier repeaters, not necessarily highest output power in saturation. Due to the necessity of using microstrip matching elements at these frequencies, and the need to tune the amplifier to various application bands, microstrip element lengths must be adjusted in some cases. The PCB design includes easily cuttable “zipper links” in the microstrip stubs which allows tuning using a hobby knife. Care must be taken when cutting links that the entire link is removed. A thin knife cut may leave copper slivers that may later reconnect and detune the amp after exposure to vibration. For this reason, use the wider back edge of the hobby or putty knife, and verify, using a magnifier, that the links are properly and permanently cut. If during adjustment, it is found that one went too far, and a link needs to be restored, this can be easily done by solder bridging. At all times, do not apply power to UUT unless both input and output are properly RF terminated. Be especially careful not to connect UUT with input and output reversed since this unit has ample capability to destroy network or spectrum analyzers. • EQUIPMENT: The following equipment is needed for execution of this procedure. q Scalar Network analyzer, 1 GHz capable. Analyzer must be normalized and calibrated per manufacturer’s instructions prior to any test session and at 1 hour intervals thereafter. q Termination calibration kit for above (type N) q Spectrum Analyzer, 1 GHz capable, input dynamic range up to +25 dBm with input intermod < -60 dBc q 50W 20 dB Attenuator good to 1 GHz. Type N. q Multimeter q 800-1000 MHz Splitter/Combiner, Isolation > 20 dB 800 MHz to 1000 MHz. (Narda 4322-2 or equivalent) q Two 10 dB fixed attenuators q Turret Attenuator with 1 dB resolution. 0-30 dB minimum range. q Broadband Linear Power Amplifier, 3W, 800-100 MHz, (Mini-Circuits ZHL-1000-3W or equivalent.) q Two synthesized signal generators capable of tuning over 800-900 MHz band with output capability of +5 dBm minimum. q Johanson capacitor trimming tool No. 8777 q Power supply cable with male Framatome “Jupiter” connector. q DC Power supply capable of 2A at 24 VDC with variable current limiting. q Customized Amplifier top cover with access holes drilled for access to C19 and R5 q Toggle press or other means for temporarily securing amplifier top lid during test. (You may use 4 screws in the corners as an alternative. q RF interconnection cables as required. Do not use between series adaptors between network analyzer and UUT RF input or between UUT RF output and high power attenuator. Note, for …

BDA’s are intended to extend radio frequency coverage into areas with coverage deficiency such as inside office buildings, shopping malls, hospitals, tunnels etc. They are designed to be located independent of the Donor Transceiver Site and are equipped with their own antenna systems - one to communicate with the Donor Transceiver Site and the other(s) to communicate with radio equipment in the area with coverage deficiency. For proper BDA System operation with no feedback problems, the RF isolation between the roof top antenna and the indoor antenna(s) must exceed the net system gain by at least 12 dB. Note that the net system gain takes into account the BDA gain, antenna gain, cable & connectors losses.
