P.G. TM0051 SECTION 1. GENERAL INFORMATION 1.1 INTRODUCTION 1.1.1 Scope of Manual. - This manual is provided to familiarize personnel installing the R307B 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 R307B Repeater is used as a drop-in booster for the SMR band (800 MHz trunking).
P.G. TM0051 TABLE 1-1 Performance Characteristics and Salient Features of the R307B Repeater Parameter 1. Input Power: 2. Frequency Range: - Base Receive (Uplink) - Base Transmit (Downlink) Specification 9 to 12 VDC @ 1 A Max. (12 VDC Adapter is supplied with the unit) 806 - 821 MHz 851 - 866 MHz Note: The following specifications apply in both directions 3. Maximum Gain: 60 dB Typical 4. Attenuator Range: 31 dB in 1 dB Steps 5. Impedance (Input and Output): 50 Ohms 6. VSWR: 2:1 Typical 7.
P.G. TM0051 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 1-2, 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. TM0051 SECTION 2. THEORY OF OPERATION 2.0 GENERAL The R307B is a bidirectional repeater, providing a maximum of approximately 60 dB gain in the SMR uplink and downlink bands. The block diagram of the R307B is shown in Figure 2-1. 2.1 - The unit is composed of amplifiers and diplexers as well as voltage regulation circuits. The downlink signal enters the unit via Base Antenna connector (the common port of diplexer U2). The signal passes through the high band port of diplexer U2 to drive amplifier 2.

P.G. TM0051 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. TM0051 3.3 OPERATING AND MAINTENANCE INSTRUCTIONS When powered, the unit will amplify signals in both the uplink and downlink bands. The unit does not require any regular maintenance. The internal independent uplink and downlink attenuators can be set by the DIP switches on the bottom of the unit. Steps are available for 1 dB, 2 dB, 4 dB, 8 dB and 16 dB of attenuation. Setting the switch to "ON" inserts the corresponding attenuation value.
