APPLICANT: Ericsson Radio Access ABFCC ID Number: OPVKRB1011047-1 TEST REPORT 50 W linear power amplifier Application for certification APPLICANT: Ericsson Radio Access ABFCC ID Number: OPVKRB1011047-1 TEST REPORT 1 APPLICATION FOR CERTIFICATION, §2.1033 (1)Manufacturer:Ericsson Radio Access AB Box 11 SE-164 93 Stockholm Sweden Applicant:Ericsson Radio Access AB Soren Norbeg Box 11 SE-164 93 Stockholm Sweden (2)FCC IdentifierOPVKRB1011047-1 (4)Type of emissions:DXW, F1D, and F8W. This amplifier is for use in the Public Mobile Service (CFR title 47 part 22 Subpart H , and according to 22.901(d) Cellular Radiotelephone Service) (5)Frequency range:869 to 894 MHz (6)Range of operating power: 1 - 50 W (7)Maximum power rating:50 W, distributed to minimum 2 and maximum 32 carriers. (8)DC voltage and current:Voltage:27±1 V DC Current:30 A (MCPA current consumption) (10) Tune up procedure:The amplifier is factory tuned. The only necessary and possible installation tuning is to adjust the RF input power level. When the amplifier is properly installed in a radio base station (as indicated in Figure 1: MCPA environment) the Cellular Radio Exchange (CRE) will supervise and control the output power per carrier. If a fault condition should arise in the amplifier, this is signalled to the CRE. In case of severe faults the amplifier is automatically shut down. APPLICANT: Ericsson Radio Access ABFCC ID Number: OPVKRB1011047-1 TEST REPORT 2 GENERAL AMPLIFIER DESCRIPTION The MCPA Cabinet is a power amplifier, for highly linear amplification of a composite input signal of up to 24 digitally or analogue modulated carriers. The amplifier power output is 50 W. The amplifier is primarily intended for use together with RBS 884 base stations.

APPLICANT: Ericsson Radio Access ABFCC ID Number: OPVKRB1011047-1 TEST REPORT 2.2 COMMENT ON FILTER FUNCTIONS To fulfil the cellular standard (e.g. IS-138-A) it is necessary to use a bandpass filter to restrict spurious emissions outside the TX-band. This filter is included in the normal base station structure (cf. Figure 1: MCPA environment) APPLICANT: Ericsson Radio Access ABFCC ID Number: OPVKRB1011047-1 TEST REPORT 2.2.1 Necessary filter performance In order to fulfil §2.1051, Spurious emission at antenna terminal, a low pass filter must be inserted between the amplifier output terminal and the antenna. The filter attenuation must greater or equal to: Frequency range (MHz) Attenuation (dB) 910 – 178845 1788 – 270020 This text is also included in the installation manual, § 1.5, “Legal information”. APPLICANT: Ericsson Radio Access ABFCC ID Number: OPVKRB1011047-1 TEST REPORT 3 RF OUTPUT POWER, §2.1046 (b) Maximum RF output power is 50 W. If the amplifier is severely overloaded, more than 2 dB, it will shut down. All the following tests are performed at 50 W output power.
