MARK-IV BROADBAND AMPLIFIERS User’s Manual 3 / 11 REV3 01/25/06 Section A. Introduction This document is the MARK-IV Broadband Amplifiers User’s Manual, intended for the Radio Technical Personnel. The Mark-IV Broadband Amplifiers are highly-linear devices suitable for applications in the two-way radio and cellular UHF and 800 MHz bands. They are intended for use in low to mid power amplification and re-amplification systems, including land-mobile radio and cellular uni- and bi-directional signal booster systems. These amplifiers utilize linear LDMOS power devices that provide high gain, wide dynamic range, and excellent group delay and phase linearity. Exceptional performance, long term reliability, and high efficiency are achieved by employing advanced matching networks and combining techniques, EMI/RFI filters, machined housings, and qualified components. Models: UHF band: M4-BBDA-U, FCC ID: TCJ-M4BBDAU 800 MHz band: M4-BBDA-8, FCC ID: TCJ-M4BBDA8 Key Features: • Solid-state, ultra-linear design • High reliability and ruggedness. • Built-in high dynamic range with Automatic Level Control (ALC) circuit. • Built-in Output Circulator • Built-in monitoring circuits, DC signal at interface connector: o Forward Power Detector o Reverse Power Detector
MARK-IV BROADBAND AMPLIFIERS User’s Manual 4 / 11 REV3 01/25/06 General Disclaimers This manual is intended to be used with the MARK-IV Equipment only. It is not to be used with any other equipment unless it is authorized by Canam Technology, Inc. Canam Technology, Inc provide this document “as is” without any warranty of any kind. This document may contain typographical errors and technical inaccuracies. Canam Technology will not accept any liability from the use and misuse of this manual, the information contained within, or the consequences of any actions resulting from the use of this information. The user can not make any modifications to the unit(s). Changes or modifications not expressly approved by the party responsible for compliance voids the user’s authority to operate the equipment. Radio-Frequency Amplifiers such as the MARK-IV generate radio signals and, therefore, electromagnetic fields. The technical personnel should have a complete understanding of FCC CFR Title 47 sections 1.1307 and 1.1310. Recommendations are included in this Manual, but they do not substitute the FCC guidelines. This device may require the use of antennas for proper functioning, depending on the application. The installation of the antennas should be performed by qualified technical personnel. All antennas should be fixed mounted and physically secured to one location. The people must be away from the antennas at least 1.0 meters to comply with the RF Human Maximum Permissible Exposure limits, as long as the antenna system gain is lower than 0 dBi. If greater gain is used the separation should be increased, please refer to the FCC Rules. If service should be performed on the antenna, please shut down the transmitter or lower its power in order to comply with the maximum permissible exposure.
MARK-IV BROADBAND AMPLIFIERS User’s Manual 5 / 11 REV3 01/25/06 Section B. GLOSSARY OF TERMS AC: Alternating Current. Broadband Amplifier: A device at a fixed location which automatically receives, amplifies, and retransmits the signals received from base, fixed, mobile, and portable stations, with no change in frequency or authorized bandwidth. All signals within the passband of the amplifier filter are amplified. DC: Direct Current. Rx: Receiver or Input Port. Tx: Transmitter or Output Port.
MARK-IV BROADBAND AMPLIFIERS User’s Manual 6 / 11 REV3 01/25/06 Section C. THEORY OF OPERATION The MARK-IV BROADBAND AMPLIFIERS are self contained modules having the RF Input and Output ports via SMA-type coaxial connectors and DC plus Control signals via D-Subminiature 9-pin connector. These amplifiers modules must be installed on appropriate heat-sinks to dissipate the heat they generate during normal operation (with or without input signal). It is recommendable the Case Temperature not to exceed 50 degrees Celsius to benefit the amplifier’s life span. The RF Input signal is amplified by the amplifier’s gain and delivered at the RF Output without changes in frequency, modulation or occupied bandwidth. Pout = Pin + Gain The MARK-IV BROADBAND AMPLIFIERS are equipped with Automatic Level Control (ALC) circuitry to limit the output power to the factory preset level, preventing that an input drive signal level plus the amplifier’s gain would exceed the maximum authorized output power level. In that case, the ALC circuit will proportionally decrease the gain as required not to exceed the preset output level. A red LED on the side of the amplifier’s case is lit when the ALC circuit is in operation. The amplifiers are also equipped with Input Overdrive Protection (passive “fuse-type”) to prevent further damage of its internal stages in case of accidental very strong signals well above the maximum input level required for normal operation. The MARK-IV BROADBAND AMPLIFIERS requires an external DC Power Supply, typical +28 VDC. They can operate at +24 VDC with approximately 1 dB reduction on gain and linearity performance. The current draw is less than 4 Amps at maximum output power.
