  • Page 53: Connecting Ac Power

    RF output Connecting AC Power The TB9100 PMU is designed to accept a mains input of 88 to 264VAC at 45 to 65Hz. We recommend that a 3-wire grounded outlet be used to supply the AC power. The socket outlet must be installed near the equipment and must be easily accessible.

  • Page 54: Connecting Dc Power

    The way you connect DC power varies, depending on the type of base station. The TB9100 PMU is designed to accept a nominal 12VDC, 24VDC or Base Station with 48VDC input (depending on the model) with negative or positive ground.

  • Page 57 Most base station manufacturers have adopted 28V LDMOS technology to Explanation benefit from its superb wide-band performance and high efficiency. Accordingly, the TB9100 uses the MRF9060 LDMOS FET as the final power device. However, LDMOS devices have a lower breakdown voltage. The circuit design of 50W and 100W PAs protects the MRF9060 from high VSWR.

  • Page 58: Connecting An External Frequency Reference

    Connecting an External Frequency Reference For K4 Band, the internal frequency reference accuracy is inadequate, and an external reference (for example, the Tait T801-02) must be used. The external reference frequency can be 10MHz or 12.8MHz, with an input level of 300mV pp to 5V pp. The stability of this reference should be better than 50 parts per billion.

  • Page 59: Connecting General Purpose Inputs And Outputs

    Connecting General Purpose Inputs and Outputs The TB9100 has a number of configurable general purpose inputs and outputs. These are connected via the 9-way D-range.

However, the PMU must be powered up to enable the I C communications to operate. Base stations which use the 12V PA do not require a PMU, and in this case the C current source is located on the base station subrack interconnect board.
