FCC Filing - SC4812T @1.9 GHz CDMA BTS Frame Cellular Infrastructure Group FCC ID: IHET6YR1 EXHIBIT #11A DESCRIPTIVE INFORMATION FCC Filing- SC4812 @1.9 GHz CDMA BTS Frame1 DESCRIPTIVE INFORMATION FCC FILING FOR SC4812T @1.9 GHz CDMA BTS FRAME The Information in this exhibit is in accordance with the FCC Rules and Regulations, Vol. II, Part 2, Subpart J. Sections 2.983 through 2.999 are addressed. Section 2.983 (a)Name of Applicant and Manufacturer: MOTOROLA Section 2.983 (b) Identification of Equipment: IHET6YR1 Section 2.983 (c) Quantity Production: Quantity Production is Planned. Section 2.983 (d) Technical Description This Transmitter is intended for use in the Public Cellular Radio Telecommunications Service and is designed in compliance with the FCC Rules and Regulations Title 47, Part 24(E).This transmitter is capable of spread spectrum (CDMA) operation, and allows up to 64 Walsh codes to support Pilot, Sync, Paging and Traffic channels. (1) Types of Emissions This equipment will be capable of operation using wide band spread spectrum techniques employing Direct Sequence Code Division Multiple Access (DS-CDMA) digital communication techniques. For this transmitter, the emission designator is 1M25F9W (per FCC Part 2.201, subpart C). (2)Frequency Range This transmitter operates within the 1930 to 1990 MHz Band (per FCC Part 24). This base station will support CDMA operations on channel numbers 25 through 1175 (1931.25 MHz - 1988.75 MHz. (3) Range of Operating Power The rated maximum average power out of the SC4812T @1.9 GHz CDMA BTS Frame is 44.88 W (46.5 dBm). However, in CDMA the actual power output is based on the number of traffic channels in operation. The minimum power occurs when only a pilot signal is present. The maximum power occurs when a pilot along with synchronization, paging, and traffic channels are present. For a typical system setup, the theoretical difference between minimum power and maximum power is 8dB. The output power is variable in 0.25 dB steps. The range is 12 dB. FCC Filing- SC4812 @1.9 GHz CDMA BTS Frame2 (3) Range of Operating Power (cont.) In addition, the dynamics of a CDMA system allow for what is called “cell breathing”. This allows an operator to vary the range of a cell by controlling the power of the pilot signal. (4) Maximum Power Limits The peak output power of a base station transmitter may not exceed 100 Watts as defined in Part 24.232 (5)Applied voltages and currents into the final transistor elements of the transmitter output: In the CDMA system, the applied voltages and currents into the final transistor elements SRF7042X4 for 44.88 W output: Drain 27.7 VDC Drain Current 1.0 AMPS x 3 Gate Voltage 4 VDC (6) Function of Each Active Device Refer to Exhibit #11B. (7) Complete Circuit Diagrams Refer to Exhibits #5A through #5M. (8) Instruction/Installation Manual Refer to Exhibit #8 (9) Tune-Up/Optimization Procedure Refer to Exhibit #10 FCC Filing- SC4812 @1.9 GHz CDMA BTS Frame3 (10) Means for Frequency Stabilization Refer to Exhibit #6F The Clock Synchronization Module (CSM/CSM2) provides clock and time signals for an SC4812T @1.9 GHz CDMA BTS Frame. In addition, it provides the primary source, a 3 MHz clock, for the transmit synthesizer in the Broadband Transceiver. The CSM/CSM2 relies on a GPS receiver, either riding piggyback onto the CSM/CSM2 card or remotely located in an integrated package with the GPS antenna as the primary time reference for the ovenized oscillator. Two types of redundancy are provided: 1)Dual CSM/CSM2 cards provide redundancy in case of primary CSM/CSM2 failure. 2) Redundancy is also provided by either a High Stability Oscillator (HSO) or a Low Frequency Reference (LFR), such as a Loran C receiver, residing in a separate slot. The HSO is provided in case of GPS system failure. The CSM/CSM2 uses the received signals as a reference to provide the required clock for the site. The CSM/CSM2 distributes CDMA time, a 19.6608 MHz clock, and a two second synchronization pulse every even second of universal time to the CDMA Clock Distribution (CCD) Cards . The CSM/CSM2 is also responsible for configuration and management of the GPS and LFR systems. CSM/CSM2 software determines on a site basis what the GPS and LFR configurations should be. For future Commercial CDMA systems, GPS and LFR configuration information could optionally be downloaded to the CSM/CSM2 from the GLI2. The CSM/CSM2 is managed by the GLI2. The High Stability Oscillator (HSO) or Low Frequency Time Reference (LFR) is used to provide a stable time reference in case of a GPS system failure or shutdown. The output of the LFR card is routed to the CSM/CSM2 cards, which derive the appropriate time references for the Frame. The current LFR is a LoranC receiver. In areas where LoranC is unavailable, the HSO may be used. FCC Filing- SC4812 @1.9 GHz CDMA BTS Frame4 (11) Means for Attenuation of Spurious Emissions Refer to Exhibit #6C Bandpass filters are employed in the transmit RF circuit to attenuate far out spurious emissions. The filter used here is of an air dielectric cavity resonator type. The baseband employs a discrete L-C 7-pole elliptic filter. This filter is used to attenuate sideband noise and close in spurious emissions. In addition, suppression of spurious radiation is obtained by proper shielding techniques. Means for Limiting Modulation Refer to Exhibits #6B and #6F In a CDMA system, the input signal (voice for example) is sampled and coded in a vocoder. This signal is then spread to 1.23 MHz by a pseudo-random spreading code. This spreading code sets the bandwidth of the spread-spectrum signal. If more than one signal is in operation (i.e. more than one voice channel), then the two signals are simply layered one atop the other within the 1.23 MHz band. So, to some extent, the bandwidth of the transmitted signal is limited by the chip rate of the PN spreading code. Primary limiting of the CDMA signal bandwidth is accomplished by the use of a programma…
