Description

The MH89728 and MH89726 are thick film hybrid devices which may be used to extend the operating range of the MT8972 (DNIC). The hybrids combine signal equalization and amplification for the receive and transmit paths on each device.

The small size of these hybrids makes MH89728 and MH89726 suitable for line card or terminal use with the MT8972. The gain of the transmit signal may be adjusted through the use of an external resistor.
