R8840 is a UMTS multi-carrier radio unit, working on 2100MHz/AWS. R8840 supports maximum 4 carriers, the output power is 60W. R8840 module consists of MCPA (multi-carrier power module) module, transceiver module, duplex filter LNA and RPWAC/DC (Power for AC or DC). There are one TX/RX port and one RX port for connecting antenna. R8840 employs compact cabinet design, as shown in Figure 16. Dimension of R8840 is 370×320×160mm (H×W×D).
R8860 is multi-carrier RF module, working on 850/900/1800/1900MHz. R8860 can be configured as GSM only, UMTS only or mixed mode module. R8860 can be configured to 1 to 6 TRX in GSM mode. In case of GMSK modulation, 80W TOC output power can be provided. If R8860 is used as UMTS mode, it can support 4 carriers with 80W TOC output power. In mixed mode, R8860 can support 4 GSM TRX and 1 UMTS carriers or 2 GSM TRX and 2 UMTS carriers.
R8880 is a multi-carrier RF module. R8880 can be configured as UMTS mode. It can process 2 received signals and 2 transmitted signals. Each one can support 2*2 MIMO in HSPA+ mode on 2100MHz. Its output power achieves up to 2*60W (TOC). It is mainly used for outdoor macro coverage and also used for indoor coverage signal source. R8880 can be configured as UMTS mode. R8880 can support 3 carriers when it ensures the 2*20W output power for each carrier.
R8882 is a multi-carrier RF module. R8880 can be configured as UMTS mode. It can process 4 received signals and 2 transmitted signals. Each one can support 2*2 MIMO in HSPA+ mode on 2100MHz. Its output power achieves up to 2*60W (TOC). It is mainly used for outdoor macro coverage and also used for indoor coverage signal source. R8880 can support 3 carriers when it ensures the 2*20W output power for each carrier.
