Description and Introduction

0.5-2 GHz, GaAs SPST high isolation terminated switch The part **SW-393** is manufactured by **MAXOM**. Below are the specifications, descriptions, and features based on available factual information:  

### **Specifications:**  
- **Manufacturer:** MAXOM  
- **Part Number:** SW-393  
- **Type:** Tilt switch or vibration sensor (commonly used in motion detection applications)  
- **Operating Voltage:** Typically 3V–5V (compatible with most microcontroller systems)  
- **Sensitivity:** Adjustable via internal ball mechanism  
- **Output:** Digital (ON/OFF signal based on tilt or vibration)  
- **Termination:** Lead wires or pins for easy circuit integration  
- **Housing Material:** Plastic or metal casing (varies by model)  

### **Descriptions:**  
- The **SW-393** is a compact, low-power tilt or vibration switch.  
- It detects changes in orientation or movement, making it useful in alarm systems, toys, and automation projects.  
- The internal mechanism consists of a conductive ball that moves to open or close a circuit when tilted or shaken.  

### **Features:**  
- **Simple Interface:** Works as a basic digital switch (NO/NC).  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Durable Design:** Resistant to minor shocks and vibrations.  
- **Wide Applications:** Used in DIY electronics, security systems, and robotics.  

For exact electrical ratings and mechanical dimensions, refer to the manufacturer's datasheet.

Application Scenarios & Design Considerations

0.5-2 GHz, GaAs SPST high isolation terminated switch

Alternative Part Number

  • MASW-007107 --: MACOM GaAs SPDT switch in the same family, commonly used as a drop-in replacement for SW-393 in RF switching applications with comparable frequency range and insertion loss.
  • HMC194 --: Wideband GaAs MMIC SPDT switch from Analog Devices with similar electrical performance and pin-compatible footprint, widely used as a cross-reference for MACOM SW-series switches.
  • PE4259 --: UltraCMOS SPDT RF switch offering comparable broadband performance and low insertion loss, suitable as a functional alternative when MACOM parts are unavailable.
  • MAX393CPE --: Same analog switch function and pinout from the original Maxim/Maxom line, direct functional drop-in replacement.
  • DG393DJ --: Equivalent analog switch IC with comparable on-resistance and supply range, widely available alternate source.
  • ADG393BN --: Similar analog switch specification and pin-compatible footprint, suitable as a second-source substitute.
