MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MDC5100/D Advance Information Antenna Switch Controller The MDC5100 is designed to control GaAs RF switches which require positive and negative going control voltages to select the switch path.
All input control signals are 3 V CMOS–logic compatible to allow for direct interface to a microcontroller.
The device also has an accessory detect pin for use in applications where there is a portable handset to mobile adapter.
The device is designed to interface directly with Double Pull–Double Throw (DPDT) switches such as the M/A–Com SW 363.
This device in combination with a GaAs RF switch can be used to achieve duplex isolation in ma...
