Antenna Switch Control
The MDC5101 inputs TxE and RxE Logic Signals with an accessory input termination option and, allows positive and negative control voltages in accordance with the enclosed truth table. This device is primarily intended to control GaAs RF switches. It is also designed to interface with most HCMOS MCUs such as the Motorola MC68338. The MDC5101 is intended to replace a circuit of up to 18 discrete components and is available in a Micro–8 package. This device, in combination with a compatible RF switch, can be used to achieve duplex isolation in any Time Division Duplex Radio like GSM and DCS1800 with staggered Transmit Receive Time Slots.
