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.

Features
