P.G.TM0032FE 1 - 4 TABLE 1-2 Rated Power Output for Linear Operation (for intermodulation products 50 dB down) The Total Composite output power in multiple tone or wideband signals shall NOT exceed the following level or else it may result in improper operation of the device and cause interference. Cellular Base Transmit (Downlink)+ 12 dBm Cellular Portable Transmit (Uplink)+ 9 dBm PCS Base Transmit (Downlink)+ 12 dBm PCS Portable Transmit (Uplink)+ 4 dBm P.G.TM0032FE 2 - 1 SECTION 2. THEORY OF OPERATION 2.0 GENERAL As explained in Section 1, the A211 is a bidirectional amplifier, which provides 20 dB of gain in both the cellular and PCS wireless transmit and receive bands. The block diagram of the A211 is shown in Figure 2-1. 2.1 DESCRIPTION 2.1.1. - The unit is composed of two diplexers, two independent bidirectional amplifiers and alarm and voltage regulation circuits. 2.1.2. - The diplexers U1 and U2 divide power between the cellular and PCS bidirectional amplifiers. In each bidirectional amplifier additional bandpass diplexers separate signals for the uplink and downlink amplifiers. 2.1.3. - The bias condition of each device in the amplifiers is monitored. If the bias changes outside certain limits a fault condition is indicated. The downlink RF output power in each band is also monitored. If the power in either band drops below established limits a FAULT condition is indicated. When a FAULT condition occurs the unit transmits the unit identification (or "Fault Code") by two level amplitude modulation of a low frequency carrier placed on the cable center conductor. The signal is transmitted as a short burst repeated at approximately 80 second intervals while the fault condition persists. The fault code can be reprogrammed as described in Section 3.2. While a NORMAL condition exists the amplifier transmits an OK code at intervals of approximately 80 minutes. This remote status transmission feature is not available when the unit is configured for local powered operation. 2.1.4. - The voltage regulators take 15 - 24 VDC input and provide 12 VDC and 8 VDC outputs. A zener diode provides transient protection against voltage spikes on the cable. 2.1.5. - The standard A211 dual band bidirectional amplifier requires external DC power to be supplied through either one of the two N receptacles. Internal jumpers are used to select whether DC current is drawn from J1, J2 or both. If configured to draw current from J1 or J2 then the unit will only pass RF between J1 and J2. Otherwise the unit will pass both DC and RF. Section 3.2 provides details on how to set up these jumpers. The local powered unit is configured to block DC to J1 and J2. The PS217 external power source is used to supply DC power to the unit. P.G.TM0032FE 2 - 2 Figure 2-1. A211 Dual Band Bidirectional Amplifier - Block Diagram P.G.TM0032FE 2 - 3 2.2 FAULT REPORTING 2.2.1 General - The A211 amplifier incorporates a number of circuits to detect deviations in important performance parameters. The standard unit (P/N 001-0211-002) reports alarm conditions to a remote Monitor unit such as the Model PS212. The local powered unit has local status indication only. The various functions are described in this section and may also be referenced in Section 4 where the programming of amplifier options is discussed. 2.2.2 Report Types (P/N 001-0211-002 only) - The Model A211 generates two types of reports depending on the status of the amplifier as determined by the built in monitor circuits. Each type consists of a numeric code sent as low frequency tones along the coaxial cable for decoding at the monitor unit. Under normal operation the unit will transmit an "OK" code at intervals of approximately 80 minutes. This enables the system monitoring unit to keep track that the whole system is connected and operational. In this mode a local green NORMAL LED lamp is illuminated on the side of the amplifier. In the event that a fault is detected in the amplifier, as described later, a "FAULT" code is transmitted on the cable at intervals of approximately 80 seconds. In this mode a local red FAULT LED is illuminated on the amplifier. Four LEDS on the side of the unit indicate which specific local condition is causing the overall FAULT condition as described in the next section. In each case the code transmitted identifies the transmitting amplifier by the FAULT CODE programmed in that particular amplifier as described later in Section 4.6. Before shipment PG programs each amplifier with a arbitrary code from 1 to 199 which is also shown by a label on the outside of the unit. NOTE: Older models of PG bidirectional amplifiers such as the A181 or A188 transmitted only fault codes, but are compatible with the fault codes transmitted by the A211. When used with a PS212 Monitor they should be entered in the ID list as "FAULT ONLY" (TFO) type units. If the A211 is used with a PS200 PS/Monitor the OK code transmission (STATUS option) should be disabled (section 4.4) as it will cause the PS200 to display a FAULT alarm. Fault codes above 199 should not be set on any amplifiers since they may be incorrectly interpreted by the newer PS212. P.G.TM0032FE 2 - 4 2.2.3 Fault Conditions - The A211 circuitry monitors four separate parameters in the unit. These are (a) the bias currents drawn by the transistors in each of the cellular and PCS amplifiers and (b) the presence of downlink RF output power in each amplifier band. Each function can be disabled as described in Section 4, if the unit is being used in a restricted operational mode. The DC current monitoring triggers a fault condition if the DC bias current deviates outside predetermined high or low current limits. The downlink RF output power from each frequency band is monitored by separate detectors and a FAULT condition is triggered if the level in either band drops below a nominal level of - 5 dBm. If the amplifier is to be installed at a point in the system where the output power in either band may be less…

The unit is a low power bidirectional amplifier for the cellular and PCS communications bands. The cellular RF amplifier circuitry is identical to the A181 previously granted authorization by the FCC. The PCS amplifier stages have a power level similar to the cellular stages. The diplexers used are fixed-tuned and the unit does not require tuning. The unit contains no oscillator or frequency translation circuitry. The unit is designed to be used for in-building signal enhancement. The unit allows operators to reduce interference problems by utilizing low power signals directed to the exact required coverage areas instead of using increased power at a distant antenna. The downlink 1 dB compression point level is 100 mW (+ 20 dBm) in both the cellular and PCS bands. The uplink compression point is at least 3 dB lower than the downlink compression point in both bands The attached exhibits contain technical information to assist you in reviewing our application and test data which has been taken under my supervision.

Response: P. G. Electronics defines the Composite Power as being the total average RMS power of all inband signals. The customer will operate the equipment at or below this total average power. The Composite Power rating is specified at 8 dB below the 1 dB compression point to ensure linear operation with low distortion with intermodulation products typically 50 dB below the carrier signals. This holds true for any number of carriers with total average power adding up to the Composite Power rating. The Test Report exhibit submitted previously (P6T81901TR) shows 3-tone intermodulation tests performed at the rated Composite Power. This information is shown in Section 2.2 in Plots 5, 7, 9, 11. If any further information is required, P. G. Electronics will provide this information as soon as possible. Sincerely. Gerry Graham P. G. Electronics
