AS173-73 General Description

The AS173-73 is a PHEMT GaAs FET IC high linearity SPDT switch in a SOT-6 plastic package. This switch has been designed for use where extremely high linearity, low insertion loss and ultra miniature package size are required. It can be controlled with positive, negative or a combination of both voltages. Some standard implementations include antenna changeover, T/R and diversity switching over 2 W.The AS173-73 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications.

AS1742 General Description

The AS1741/AS1742/AS1743 are high-speed, low-voltage, dual single-pole/single-throw (SPST) analog switches. Fast switching speeds, low ON-resistance, and low power-consumption make these devices ideal for single-cell battery powered applications.

These highly-reliable devices operate from a single +1.6 to +3.6V supply, and are differentiated by the type and number of switches:

AS1741 Two normally open (NO) switches
AS1742 Two normally closed (NC) switches
AS1743 One NO switch and one NC switch

The AS1743 supports break-before-make switching. With very low ON-resistance (RON), RON matching, and RON flatness, the devices can accurately switch signals for sample and hold circuits, digital filters, and op-amp gain switching networks.

The AS1741/AS1742/AS1743 digital logic input is 1.8V CMOS-compatible when using a single +3V supply, and all devices can handle Rail-to-Rail signals. The devices are available in an 8-pin SOT23 and MSOP package.
