Exhibit 2 Active Antenna FCC Type Acceptance7/10/01 FCC ID NMFAAGSM191250M 1 Exhibit 2Function of Each Active Circuit / Circuit Diagrams : 2.983 (d)-9, 7, 11 Exhibit 2 provides technical information on the function and design of each of the active circuits used in the Active Antenna. Specific items included in Exhibit 2 are listed following Included Items 1. HPA Circuit Card Assembly (CCA) 2. LNA Circuit Card Assembly (CCA) 3. DC / Fault Circuit Card Assembly (CCA) 4. Calibration Circuit Card Assembly (CCA) 5. Bandpass filter characteristics (2.983 (d) -11) 2-1 HPA Circuit Card Assembly (Power Amplifier, 2.4 Watt, Qty 3 per Channel) Figure 2-1 HPA CCA Block Diagram Three high power amplifier (HPA) cards are used in each transmit channel. Figure 2-1 shows a block diagram of the HPA circuit card assembly (CCA). Each HPA CCA is a three stage linear power amplifier with a rated power output of 35.5 ± 0.5 dBm. All three stages are Gallium Arsinide (GaAs) HFET type devices. The CCA includes on board power regulation, current sensing for fault isolation, an output isolator, and an adjustable attenuator used during manufacturing to adjust the power output to the nominal value noted. The input to the amplifier is through a 7db temperature compensating attenuator with a .007 dB/dB °C slope to flatten the response. The compensated amplifier produces the maximum output power at room temperature, where the output power is adjusted, and falls off at either temperature extreme. (See Figure 4-2 in Exhibit 4 for the amplifier’s temperature response.) The CCA uses 100% surface mount components. Circuit schematics are provided in Exhibit 3 and a photograph is included in Exhibit 9.

This card accepts the –48VDC prime power input supplied by the PBC and provides regulated, filtered drive voltages for the HPA and LNA circuit cards. Two redundant power supplies and filtering circuits are packaged on a single card to improve overall reliability of the system. If the primary supply fails, it is switched offline and the redundant supply takes over. Figure 2-3 shows a block diagram of the DC suppy portion of the circuit card. It contains switching DC - DC power converters running at 250 / 500 KHz, power regulation and filtering circuits, and surge suppression circuits.

The microprocessor is a 16 bit Motorola 68HC12 running at 16 MHz. It handles the control commands from, and responses to the PBC via an RS-485 data link which runs over a single shielded twisted wire pair. During normal operation, the processor monitors discrete fault lines from the power supply and each of the amplifier circuits. It formats this information into two, 16 bit alarm response words that are supplied to the PBC upon interrogation, approximately once per second. On operator command, via the PBC control panel, the processor will also: supply the software version number, disable the HPA’s (in preparation for calibration), set the internal attenuators to the proper drive level, re-enable the HPA’s, set the internal attenuators to maximum (normal position when leaving the factory), and download an event log containing a limited history of commands, responses, and alarms. When commanded to set the attenuators, the controller begins the calibration sequence by automatically resetting the attenuators to their maximum value. It then steps the value down until a logic signal from the detector in the calibration circuit (see section 2-4) indicates that the drive level is correct to generate a 500 W EIRP signal from the HPA’s. The required attenuator setting for each channel is then written to non-voltile memory. If an acceptable level is not found, the attenuators are returned to the maximum value and a fault message is sent to the PBC. Circuit schematics are included in Exhibit 3 and a photograph of the card is shown in Exhibit 9.

It operates in the 1900 MHz spectrum allocated to Broadband PCS (Personal Communication Systems). The Active Antenna applies Active Phased Array Antenna technology to the problem of improving the coverage and useful communications range of fixed infrastructure radio equipment. It is designed to work as an option with the Ericsson 2302 Radio Base Station (RBS) and Power Battery Cabinet (PBC). The Radio Base Station provides the signals for amplification while the Power Battery Cabinet provides the DC power and alarming interface for the Active Antenna. Figure 1 illustrates the Active Antenna and the related equipment. This product is similar to a previous Raytheon TI Systems (RTIS) Active Antenna product (reference FCC ID NMFAAGS1912501C1B) but it receives its power and control signals directly from the Ericsson PBC, whereas the previous product provided these functions with an additional, external interf…

Exhibit 4 Active Antenna FCC Type Acceptance7/10/01 FCC ID NMFAAGSM191250M 1 Exhibit 4RF Power Output: 2.983 (d)-3, 2.983 (d) -4, 2.985 (a) The Active Antenna complies with the maximum EIRP limit of 1640 Watts as specified in 47 CFR 24.232. The EIRP of the Active Antenna is determined by the sum of combined output power of the internal transmit amplifiers and the gain of the radiating array. This exhibit provides measurements of: the combined output power of the amplifiers as measured in the laboratory, the gain of the radiating array, and field measurements of the total, combined EIRP Each set of data includes a block diagram of the test set up, list of test equipment, description of the test sequence, and test data. Specific items included in Exhibit 4 are listed following. Included Items 1. RF power Output at the Combined Amplifier Power Reference Point - 2.983(d)-3 2. Range measurement of radiating elements 3. Active Antenna RF power output - field measurements Exhibit 4 Active Antenna FCC Type Acceptance7/10/01 FCC ID NMFAAGSM191250M 2 4-1 RF Power Output at the Combined Amplifier Power Reference Point - 2.983(d)-3 The Active Antenna contains three amplifier channels, each of which is connected to an antenna subarray of four radiating elements. To measure the combined RF output power, the antenna elements are removed and a passive test combiner of known loss is used to sum the output of the three amplifiers into a single output. The unit was measured in a temperature chamber and RF output data was collected at three temperatures, -35 ° C, +25 °C, and + 55 ° C. For each test, the input port of the Active Antenna is driven with an unmodulated signal source at +20.5 dBm (100 mW) power input which allows the sum of the power amplifiers to reach full rated power of 38.5 dBm (7.1 W) total. The test diagram is shown in Figure 4-1 and the list of test equipment is provided at the end of this exhibit.

To confirm this measurement, the EIRP of the complete system was measured on a far field antenna range. To measure EIRP, the antennas are mounted on a 100’ antenna test tower with the receiving equipment located on a similar tower, 400’ downrange. Reflection fences are used to minimize ground reflections. First, a signal source is configured to deliver a fixed power between 20.5 and 32.5 dBm into a reference antenna with a known gain. The received signal strength is then measured downrange at 5 MHz increments across the appropriate sub-band. The reference antenna is then replaced with the Active Antenna. The Active Antenna is commanded to calibrate the input drive level and the internal attenuator settings are noted. The new received signal strength is then recorded at each frequency. From this, the EIRP of the Active Antenna is calculated by adding the difference in received power levels and the internal attenuator settings to the gain of the reference antenna. The test unit was configured with a set of filters for each of the three bands. Results for these measurements are given in Figures 4-5, 4-6, and 4-7. All three bands are in compliance with the +62 dB (1640 W) limit…

Each set of data includes a block diagram of the test set up, list of test equipment, description of the test sequence, and test data. Specific items included in Exhibit 5 are listed following. Included Items 1. Spurious Emissions at the Antenna terminals 2. Spurious Emissions Radiated Directly from the Cabinet 3. Spurious Emissions - Field Measurements Exhibit 5 Active Antenna FCC Type Acceptance7/10/01 FCC ID NMFAAGSM191250M 9 5-1 Spurious Emissions at the Antenna Terminals Test Configurations The Active Antenna has two transmit paths, each of which contains three amplifiers. Each amplifier is connected to a subarray of four antenna elements. To measure the purity of the output spectrum of the power amplifiers, it is necessary to disconnect the antenna and observe the spectrum of each of the three channels at the filter output coaxial connection where the normal attachment to the radiating elements is made. The amplifiers were driven to their maximum rated output power (2.4 Watts each) with a GMSK modulated signal source and the output spectrum was measured from 10 Khz to 20 Ghz. Data was collected at each of the five output ports for both transmit paths. Figure 5-1 shows the test configuration. Lists of test equipment and calibration data are included at the end of this section. Figure 5-1 Test Configuration for Spurious Emissions at the Antenna Terminals Test Results The limit on spurious emissions was computed from 47 CFR 24.238 to be 43 + 10 log P, where P is the combined output power of the five amplifiers (7.1 W), or 43 + 10 log (7.1) = -51.5 dBc. The spectrum was observed to a level of -70 dBc. Test results showed no observable spurious energy at the antenna terminals for any of the five channels on either transmit path. Based on this the Active Antenna’s amplifiers were determined to be compliant with the limitations on spurious energy.
