RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 1 of 6 Multiple Carrier Power Amplifiers Model: 45W UMTS 850 MHz MCPA Operation Instruction Date: January 25, 2007 Version. 1.0 Ref# RE: FCC ID S8L-100252MCPA RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 2 of 6 Introduction This document presents description of the Andrew Corporation 45W UMTS 850MHz MCPA (Multi-Carrier Power Amplifier). The MCPA amplifier is a high power, low distortion RF amplifier intended to provide signal amplification and conditioning. The MCPA amplifier is compatible with the UMTS WCDMA air interfaces operating in U.S. domestic cell sites where FCC compliance is mandatory. The 45W UMTS 850MHz MCPA operates in the Cell band (869 MHz to 894 MHz) and is capable of amplifying up to 2 input signals of the same UMTS WCDMA modulation types to a composite power level of 45 Watts. MCPA Specifications The 45W 850MHz MCPA provides linear amplification of multi-carrier UMTS signals in the cellular bands. The MCPA has the following specifications: Parameter Specification Operating RF Band 869-894 MHz Instantaneous BW 10 MHz Input DC Power 357Watts max DC voltage input range -36 VDC to -60 VDC, -48 VDC, nominal Rated Output Power @-48 VDC input 45W average DC-RF Efficiency 14%, rated output power, nominal input voltage Input signal types UMTS WCDMA Physical dimensions 335mm(H)X450mm(W)X400mm(D) Weight < 23.2 lbs Cooling technique Integral forced convection heat sink. Need external fan tray for forced air cooling. Temperature Range -5°C to +55°C operational and meeting specifications. Table 1 MCPA Specifications RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 3 of 6 The MCPA amplifier has been designed to support a max instantaneous bandwidth of 10 MHz which is equivalent to the 2 carrier UMTS WCDMA signal. The MCPA amplifier has a nominal gain of 46.5dB and is less than 1dB variation over the operating temperatures. The nominal RF input power is 0dBm. Functional Blocks: The Andrew MCPA is comprised of the following functional areas: − Pre-distortion circuit which comprise small signal gain stage, vector modulator and coaxial delay line − Main amplifier stage which comprise two high power modules, output isolator and gain control circuit − Power conversion and conditioning circuit − Controller circuit − Communications circuit Inputs and Outputs: The amplifier is powered from a DC supply voltage, which can range from -36V to -60V. The DC power is brought into the amplifier through a 3 pins D-Sub connector located on the front panel of the amplifier. A switch also located on the front panel is to turn on/off the DC power of amplifier. A 25-pin D-Sub connector located on the amplifier front panel is used for RS-485 communication. Alarms and operating state are communicated to the outside world through the RS-485 communications bus, and visible bi-color LED located on the amplifier front panel. The RF signal is brought into the amplifier through a pair of female SMA type connectors located on the front panel of the amplifier. The RF1 input connector is used by default and the RF2 input is for backup. The amplifier RF signal is brought out of the amplifier through an N type connector located on the front panel of the amplifier. RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 4 of 6 Control System: The MCPA will work with the customer BTS which control and monitor the MCPA by the specified interface protocol. A microprocessor controller is inside the MCPA to be compatible with the customer interface protocol and assures the MCPA performance meet the specification. The micro- processor controller is used to enable the PA to start/stop working, control the amplifier alarm system, control environmental compensation of the amplifier, and to maintain a linearization solution for the pre-distortion circuit. Figure 1 45W UMTS 850MHz MCPA Front Panel The following table is a summary of detailed alarms within the PA Module. The alarms are mapped to front panel bi-color LED behavior, as indicated. Additionally, the alarms messages are sent to the BTS by the RS-485 communication bus. Bi-color LED DC power Switch RS-485 communication connector DC power connector RF output connector RF input connector RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 5 of 6 Condition Alarm Type LED color Comments Initial Power On (RF disabled), no alarms - Red Wait for RF enable command Normal Operation – RF enabled - Green - High temp, Major Red Happen when the MCPA internal detected temperature is higher than 90C. The MCPA will shut down DC power consumption overload Major Red Happen when the DC consumption Power exceed the maximum available DC power. The MCPA will shut down RF overdrive Minor Red Happen when the RF input power is 6dB higher than the nominal value. The MCPA will Shut down Linearizer Minor Red Happen when the MCPA linearity performance worsens than the pre-defined threshold and the condition last more than 30 seconds. The MCPA will shut down Device health and Internal Voltages out of range Minor Red This alarms include many scenarios, but all related with the device performance degradation So it’s always others alarms accompany with this alarms Gain out of range Minor Red Gain is not in the specified range even with the gain compensation. The MCPA will Shut down DC-DC Converter shut down Major Red The MCPA will Shut down Table 2 Alarm mapping for PA Module RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 6 of 6 Installation and Operation Set-Up The MCPA is easy to operate and use. All the require connections is located on the front panel of the MCPA where is easy to access. The M…
