Signal switches, multiplexers, decoders and other components are widely used in various fields such as electronics, communications, automotive, medical, industrial and military applications. FST16245MTD is a signal switch particularly designed for mobile application and is part of the Small Form Factor Switch family from Fujitsu.

FST16245MTD is a Rad-Tolerant voltage controlled switch that provides controlled, wideband switch isolation and low loss performance. It supports single-pole single-throw (SPST) logic-level operation, providing up to 13 dB isolation between the device\'s switch ports at 30 MHz. In addition, the FST16245MTD features low switch power insertion loss and high frequency operation to 1.2GHz with typical 0.6 dB insertion loss. This makes it ideal for RF applications.

FST16245MTD switches are available in two different versions. The first is the FST16245MTD-A which has a 6-Volt P-channel MOSFET switch and is designed for telecom and datacom applications. The second version (FST16245MTD-V) has a larger 10-Volt N-Channel MOSFET switch and is designed for applications where high voltage switching is required. Both versions use low-on-resistance CMOS logic control, providing fast, low-power switching in a wide variety of mobile applications.

The FST16245MTD switch can be easily integrated into mobile or base station vendors’ design requirements. It offers reduced power consumption, low on-resistance, low noise and low input capacitance. The chip runs off of a single-ended +3.3V logic supply, while both the control and switching ports come in an SOIC16 package. It draws no current from the switching port, making it ideal for mobile application and maximized efficiency.

FST16245MTD operates at a voltage range of "-50V to +50V" and an input voltage of "+2.5V to +6V" at the control interface. The FST16245MTD is designed for a wide range of applications including Wi-Fi, GSM/GPRS, and Bluetooth implementations. It has a wide frequency range from 10 MHz up to 1.2GHz, and its operating temperature range is from -40°C to +85°C.

The FST16245MTD switch works by controlling currents through the device. When the FST16245MTD’s control voltage is applied, a current is supplied to the switch port and the voltage across the switch port is then changed. This in turn alters the on-resistance from the device. The resistance of the switch depends on the voltage applied and can reach a minimum of 0.2 ohms.

The FST16245MTD is a reliable and robust switch ideal for the challenging mobile market. Combining high isolation, low insertion loss and low on-resistance with single supply operation and low standby power, this switch is well-suited for many demanding applications.
