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

• Micro–miniature Low Profile Micro 8 Package

• 3 V CMOS Logic Control Inputs

• Ultra–low Quiescent Current of 400 mA Typical

• Wide Operating Temperature Range of –40 to 85°C

Applications

• GSM and PCS Portable Phones

• Mobile to Portable Accessories

• Wireless LAN Modems

• Specialized TDD and TDMA Radios

• Dual Band Phones
