P.G. TM0054RB SECTION 1. GENERAL INFORMATION 1.1 INTRODUCTION 1.1.1 Scope of Manual. - This manual is intended to familiarize personnel installing the R280 Repeater with all pertinent aspects of the repeater. Included in this manual are a brief physical description, a technical summary, and installation and operating data. 1.1.2 Purpose of Equipment. - The R280 Repeater is used as a wireless repeater. The repeater can be configured for either the cellular or PCS band of operation.
P.G. TM0054RB TABLE 1-1. Performance Characteristics and Salient Features of the R280 Repeater Parameter Specification 1. Input Power: 11 to 15 VDC @ 6 A Max. (negative ground) 2. Frequency Range: - Base Receive (Uplink) - Base Transmit (Downlink) See Tables 1-2 and 1-3 See Tables 1-2 and 1-3 3. Bandwidth See Tables 1-2 and 1-3 Note: The following specifications apply in both directions 4. Maximum Gain: 70 dB Typical for PCS units 75 dB Typical for cellular and SMR units 5.
P.G. TM0054RB 1.2 UNIT CONFIGURATION The R280 is available in various configurations.
P.G. TM0054RB For 1900 MHz Band Units: R280 P - XX Specify PCS blocks of operation (maximum of two). See Table 1-3 below. Specify P for PCS Band of Operation: For example the R280P-DE is a PCS band repeater covering the both the D and E blocks. Table 1-3 below lists the frequencies of operation for the configurations available for the 1900 MHz band.
P.G. TM0054RB NOTE IMPORTANT RATING INFORMATION Manufacturer’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced as per Table 1-4, especially where the output signal is re-radiated and can cause interference to adjacent band users. This output power reduction is to be achieved by reduction of input power or by gain reduction and not by an attenuator at the output of the device.
P.G. TM0054RB SECTION 2. THEORY OF OPERATION 2.1 THEORY OF OPERATION The R280 is a bidirectional repeater, providing gain in both the uplink and downlink frequency bands. The block diagram of the R280 is shown in Figure 2-1. The PCS unit has a typical gain of 70 dB in both the uplink and downlink bands. The cellular and SMR units have typical gains of 75 dB in both the uplink and downlink bands. The unit is composed of IF conversion modules, amplifiers, and diplexers as well as a control module.
P.G. TM0054RB External DC power is fed to the unit through the DIN power jack on the bottom of the unit. Power is fed from this module to the Uplink Amp, Downlink Amp and Controller modules. The IF conversion modules obtain their power through the Controller module. The interface module contains two LED indicators. The red LED indicates a PLL unlock condition and may illuminate briefly when the unit is first switched on while the PLLs are locking and the modules are disabled.

P.G. TM0054RB SECTION 3. INSTALLATION, OPERATING AND MAINTENANCE INSTRUCTIONS 3.1 UNPACKING AND INSPECTION The following checks are recommended after receipt of the equipment from shipping agent: 1. Check for any external damage that could have occurred in transit. If damage is found, report to the shipping agent and to the supplier immediately. 2. Check that all items on the packing slip are present. If any are missing, report to the supplier immediately. 3.
P.G. TM0054RB 3.3 R280 INSTALLATION NOTE: The unit attenuator has been factory set to the maximum value (30 dB) at time of shipment. This results in a typical unit gain of 40 dB. The installer must know the base station signal level to be fed into the unit. The gain of the unit must be set to a value such that the Rated Output Power of +19 dBm is not exceeded. The unit must not be operated above this Rated Output Power as specified in Tables 1-1 and in 1-2.
