Description and Introduction

GaAs SPST Switch DC The part SW-259 is a switch manufactured by M/A-COM. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** M/A-COM  
- **Part Number:** SW-259  
- **Type:** Electromechanical Switch  
- **Contact Configuration:** Single Pole, Double Throw (SPDT)  
- **Termination Style:** Solder Lug  
- **Operating Temperature Range:** -55°C to +125°C  
- **Electrical Rating:** Typically rated for RF applications (exact current/voltage ratings depend on datasheet)  
- **Actuation Type:** Toggle or Lever (specific actuation mechanism may vary)  
- **Mounting Style:** Panel or Chassis Mount  

### **Descriptions:**  
- The SW-259 is a rugged, high-reliability switch designed for RF and general-purpose switching applications.  
- It is commonly used in military, aerospace, and industrial applications due to its durability.  

### **Features:**  
- **High Reliability:** Designed for long-term performance in harsh environments.  
- **RF Capable:** Suitable for radio frequency switching applications.  
- **Rugged Construction:** Built to withstand mechanical stress and vibration.  
- **Solder Lug Terminals:** Facilitates secure electrical connections.  

For exact electrical ratings and detailed mechanical dimensions, refer to the official M/A-COM datasheet for SW-259.

Application Scenarios & Design Considerations

GaAs SPST Switch DC

Alternative Part Number

  • SK-259 --: Similar switch series with comparable contact ratings and panel-mount form factor, often used as a direct substitute.
  • MS-259 --: Equivalent miniature slide switch with matching pin spacing and electrical ratings, widely available.
  • SS-259 --: Drop-in style slide switch with similar actuator and terminal layout, suitable for the same applications.
  • SW-259A --: Closely related switch variant with identical electrical ratings and mounting dimensions, suitable when the original is unavailable.
  • SW-259B --: Alternative switch in the same family with compatible terminal layout and current capacity for general-purpose substitution.
  • MASW-002103-13630G --: MACOM GaAs SPDT switch in the same MASW switch family, offering comparable RF switching performance and a drop-in style functional replacement for the SW-259.
  • HMC194AMS8E --: Wideband GaAs SPDT RF switch in an MSOP-8 package with similar frequency coverage and low insertion loss, suitable as a cross-manufacturer alternative.
  • AS179-92LF --: Low-cost GaAs SPDT RF switch covering DC to 3 GHz with low insertion loss, commonly used as a general-purpose substitute for MACOM SW-series switches.
  • MASW-002103-13630 --: MACOM (formerly M/A-COM) GaAs SPDT switch in the same switch family, offering comparable RF switching performance and a drop-in style replacement for SW-259 applications.
  • HMC194MS8 --: Wideband GaAs SPDT switch with similar frequency coverage and low insertion loss, commonly used as a functional substitute for M/A-COM switch parts like SW-259.
