RF switches are components that control the flow of signals in a circuit. They are used in wireless communication systems to connect and disconnect antenna ports and other RF signals. The NJG1516R-TE1 is a low cost, high performance RF switch designed for use in a wide range of applications, such as WLAN routers, GPS systems, automotive systems, and other wireless communication applications. This article will discuss the application field and working principle of the NJG1516R-TE1.

Application field
The NJG1516R-TE1 is a two-stage single-pole double-throw (SPDT) switch with a shielding rating of up to 30dB. It is designed to provide excellent isolation between ports and has a low insertion loss and high isolation. The switch features low DC power consumption (<60mA) and is RoHS (Restriction of Hazardous Substances) compliant. The NJG1516R-TE1 is ideal for applications in WLAN routers, GPS systems, automotive systems, and other wireless communication applications. It is well suited for antenna selection, transmit/receive switching, and RF signal routing applications in a variety of wireless communication systems.

Working principle
The NJG1516R-TE1 uses a diode-clamped PIN diode to construct its two stages, both driven by the same bias voltage. The first stage is a single-pole single-throw (SPST) switch and the second stage is a single pole double-throw (SPDT) switch. When the bias voltage is applied to the switch, the PIN diode acts as a short, connecting the input and output signal paths. When the bias voltage is removed, the PIN diode is non-conductive, isolating the signal paths. The switch provides a high level of signal isolation and is also very low power, making it suitable for use in portable wireless applications.

In order to increase the isolation performance, the switch uses a shielding material to shield the PIN diode from external interference, improving the performance of the switch. The NJG1516R-TE1 also features integrated ESD protection diodes to protect the switch from Electrostatic Discharge (ESD) damage. Finally, the switch features gold-plated contacts, ensuring reliable and repeatable switching performance over a long period of time.

The NJG1516R-TE1 is a low-cost, high-performance RF switch suitable for a wide range of applications in WLAN routers, GPS systems, automotive systems, and other wireless communication systems. It offers high isolation and low insertion loss, as well as low power consumption and ESD protection. The NJG1516R-TE1 is an ideal choice for antenna selection, transmit/receive switching, and RF signal routing applications.
