SMP1320-017LF Application Field and Working Principle

SMP1320-017LF is a moderate power RF diode designed for high speed operation. The rated power of this device is 0.8W, the operating frequency range is from DC to 18GHz, and the specified return loss is +/- 2.0dB. It has the typical characteristics of high speed switching, high isolation and wide dynamic range.

Due to its unique design, this RF diode is widely used in a variety of applications, such as radar applications, communication systems, electronic countermeasures, electronic warfare, and test and measurement equipment. On the other hand, it is also widely used in industrial, scientific and medical applications such as high power amplifiers and pulse generators.

The working principle of SMP1320-017LF diode can be attributed to its structure and composition. This RF diode is based on a double-sided epi planar configuration. It consists of an anode and a cathode, a high resistivity semi-insulating substrate, a thin active layer consisting of poly-silicon, and a thin-film electrode on the surface of the active layer. The design of this diode ensures that the conduction current is uniformly distributed, and that the capacitive elements in the circuit are effectively minimized. This ensures a long service life and reliable performance.

Furthermore, the thin-film electrode acts as a current flow control, preventing undesired reverse current flow. This feature increases the immunity of the device to ESD, EMC and surge rating. In addition, the thin-film electrode also enhances the performance of the device at high frequencies, due to the reduced capacitance throughput. This, in turn, allows for high-speed operation and uniform current flow.

In summary, SMP1320-017LF is a high power RF diode suitable for a wide range of applications. It features high speed operation, high isolation, wide dynamic range and long service life. Its unique design makes it versatile and highly reliable, making it an attractive choice in industrial, scientific and medical applications.
