The **D4C0106N-R60C** is a specialized high-performance coaxial switch, typically used in RF (Radio Frequency) and microwave applications. It is designed to route signals between different paths with minimal loss and high isolation. --- ### 1. General Specifications The device is a **SP6T (Single Pole Six Throw)** electromechanical coaxial switch. This means it has one common input port and can toggle between six different output ports. | Parameter | Description | | :--- | :--- | | **Switch Type** | SP6T (1 Input, 6 Outputs) | | **Actuator Type** | Normally Open | | **Frequency Range** | DC to 18 GHz (Typical for D4 series) | | **Voltage** | 12V or 28V DC (Depending on specific coil configuration) | | **Connector Type** | SMA (Female) | --- ### 2. Key Electronic Features #### A. RF Performance * **Insertion Loss:** Designed to have very low signal degradation (usually <0.5 dB at high frequencies). * **Isolation:** High isolation ensures that the signal does not "leak" into the inactive ports (typically >60 dB). * **VSWR (Voltage Standing Wave Ratio):** Low VSWR (usually <1.5:1) ensures impedance matching and prevents signal reflection. #### B. The "Normally Open" Mechanism In a "Normally Open" configuration, the switch does not remain connected to any port when power is removed. Each of the six positions must be energized by a specific control voltage to close the circuit to that port. #### C. Actuator and Control * **Solenoid Drive:** The switching is performed by electromagnetic solenoids that physically move the internal contacts. * **Switching Speed:** Usually in the range of 15ms to 20ms. --- ### 3. Pinout and Internal Logic The "R60C" suffix often denotes specific internal wiring or control features: 1. **Common Pin:** The ground or return path for the control voltage. 2. **Select Pins (1-6):** Applying the rated voltage to a specific pin activates the corresponding RF path. 3. **Indicator Circuit (Optional):** Some models include auxiliary contacts to provide electronic feedback to a microcontroller indicating which port is currently active. --- ### 4. Common Applications * **Automated Test Equipment (ATE):** Switching between multiple devices under test (DUT). * **Telecommunications:** Routing signals in base stations or satellite uplinks. * **Matrix Arrays:** Building complex RF signal routing matrices.
