CWWP10XXUH1AMPLIFIER

P10XXUL1 and P10XXUH1 Power Amplifier User’s Manual 1. General Information. Power Amplifier (PA) is the AB/C-class unit. It is intended for amplification of single carrier phase (frequency) modulated (manipulated) narrowband signals. Working frequency range lies between 403 MHz and 470 MHz for UL unit (P10XXUL1) and between 450 MHz and 512 MHz for UH unit (P10XXUH1). Code “xx” shows the input power range: Code: R1 R2 R5 1 2 5 10 20 Range, W: 0.1-0.2 0.2-0.5 0.5-1.0 1.0-2.0 2.0-5.0 5.0-10 10-20 20-50 In the normal operating mode the minimum output power is 100 W. Input VSWR is not greater than 1.7:1. PA meets all FCC requirements to harmonic and spurious levels. The nominal power supply voltage is 13.8VDC. DC current consumption does not exceed 25A at 13.8V Working ambient temperature range lies from -30 ºC to +60ºC. Input and output power levels are set up in the factory. Customer has an opportunity to reduce the output power, adjusting the special trimmer resistor in the unit, or picking up the value of outer resistor, connected to PA control pin. PA has automatic power control loop that provides the stability of output power during the normal operation and all necessary changes of power in the case of load mismatch or unit overheating. PA is intended for rack mounting in the standard 19” cabinet. The front panel is 10” high. The deepness of unit does not exceed 5”. Four LED at the front panel indicate the status of unit operation. The hole in the side wall gives an access to the trimmer resistor, which allows reducing the output power against the set value. There are two N connectors at the back of chassis. There is power filtering DC connector at the back of chassis with four # 6-32 screws: 2 for “+” pole and 2 for “-“ pole. There are 3 filters at the back of chassis that bring alarming signal, as well signals for the outside power control. Two fans at the back side of unit perform the forced air cooling. Fans start rotating, when RF signal comes to the unit input. 2. Installation Guide. 2.1. Unit installation shall provide a proper air access to the unit; no obstacle for air is allowed closer than 3” from fans. 2.2. Copper wires # 10 AWG shall be use in DC power line. Wires shall be crimped to ring terminals. 3. Operation Guide 3.1. Power supply voltage shall be in the range 13.8 V + 1.0 V. 3.2. The input power inside the working frequency range shall be within the listed above limits. It is prohibit applying any RF signal out of the working frequency range with a power, greater than 10% of the minimum rated one. 3.3. Green LED “DC ON” is on, when DC voltage is applied to the unit. 3.4. Red LED “LOW POWER” is on, when the output power drops below 80% - 85% of set level. In majority of cases it warns about of inside problem. However, the output power may fail due to high load VSWR (in that case LED tells that the power decrease is stronger, then it is needed for VSWR protection). 3.5. Red LED “HIGH VSWR” is on, when the load VSWR exceeds 2.4 – 3. The output power is reduced. 3.6. Red LED “HIGH TEMP” is on, when the heatsink temperature is over +85 ̊C. Then the unit operates with output power, reduced to about 75% of rated one. Fans are running continuously, no matter, is RF drive applied or not. 3.7. Voltage at filter “ALARM” is about 9.5V during the normal unit operation and drops to less than 0.5V, when any of mentioned above red LED goes on. If 1.8 kOhm resistor is connected between this filter and the ground, TTL compatible output is created. 3.8. It is possible to significantly reduce the output power, pulling filter “SH/D” to the ground. However, it is possible to change the output power smoothly by a trimmer resistor (50 kOhm is the recommended value of it), connected between this pin and the ground. 3.9. The output power drops to about 75% of rated level, if the filter “CTRL” is pulled to the ground.

1/25/2011 Page 1 of 3 FCCID: FCC RF Exposure Requirements General information : FCCID: Device category: Fixed per Part 2.1091 Environment: Uncontrolled Exposure Fixed devices that operate under Part 90 of this chapter are subject to routine environmental evaluation for RF exposure prior to equipment authorization or use if they operate at frequencies of 1.5 GHz or below and their effective radiated power (ERP) is 1.5 watts or more. However, compliance with the power density limits of 1.1310 is not required. Antenna: The manufacturer does not specify an antenna. A typical fix mounted antenna has a gain of 3 to 7 dBi. This device has provisions for operation in fixed locations. Configuration Antenna p/n Type Max. Gain (dBi) Fix Any omni 3 – 7 Operating configuration and exposure conditions: The conducted output power is 100 Watts. In repeater operation duty cycle can reach near 100 %. The manufacturer also markets this device only for occupation use. But, typical installations do not control exposure. - Part 2.1091 states that devices are excluded from routine evaluation if the EIRP is less than 2.46Watt (or 1.5WERP). - A typical fixed installation consists of an antenna system with a coaxial cable of the type RG 213U which has a loss of 1.0 dB for a length of 30 feet at UHF frequencies. A repeater system typically uses outdoor structures for antenna mounting. 1/25/2011 Page 2 of 3 FCCID: MPE Calculation : The minimum separation distance is calculated as follows: The limit for uncontrolled exposure environment above 300 MHz is f/1500 mW/cm 2 . Frequency: 450-470 MHz The conducted power output is 100 watt. The coax loss was taken as 1.5 dB. Antenna gain was taken as 3 – 7 dBi 100% talk time in 30 minutes Power Density = S= f/1500 mW/cm 2 1/25/2011 Page 3 of 3 FCCID: Conclusion: The device complies with the MPE requirements by providing a safe separation distance of 3 m 123 inches) between the antenna, including any radiating structure, and any persons when normally operated. The minimum safe operating distance between the public and the antenna should be at least 3.2 m (10 ft) when used with a 7 dBi antenna.
