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 many Time Division Duplex Radios like
DECT or in Frequency Division Duplex Radios employing time
division multiple access with staggered Transit/Receive time slots
such as GSM. It can also be used to control an RF switch in dual band
radio applications. The device is housed in a miniature Micro–8 for
minimum space utilization.
