Skyworks Solutions SMP1340-040LF's Features
In terms of electrical performance, its resistance performance is excellent. Under a current of 10mA, the typical resistance value is only 0.85Ω, which greatly reduces the power loss during signal transmission and ensures efficient signal transmission. Its capacitance characteristics are also remarkable. Under a voltage of 5V, the typical capacitance value is 0.21pF. The low capacitance effectively reduces signal distortion and interference, ensuring the signal quality and showing significant advantages in high-frequency applications.
From the perspective of physical characteristics, it adopts the low-inductance Green™ SOT-23 package, and the lead inductance is as low as 0.4nH. This package can not only reduce electromagnetic interference but also improve the stability and reliability of the product. Moreover, this product complies with the RoHs standard and is an environmentally friendly device, meeting the requirements of modern electronic products for environmental protection.
In terms of performance stability, it has a short carrier lifetime, with a typical value of 100ns. Combined with the thin I-region width of 5μm, it achieves a fast switching speed and can operate stably in application scenarios with high-speed switching. In addition, both its operating and storage temperature ranges are from -65°C to +150°C, adapting to a variety of complex environments and demonstrating good environmental adaptability.
Skyworks Solutions Inc. SMP1340-040LF's Applications
In the field of high-speed wireless communication, relying on its fast switching speed and low capacitance characteristics, it can be used for the wireless signal switching of devices such as mobile phones and base stations. Within the frequency band from 10MHz to over 10GHz, it can efficiently achieve rapid switching between different channels and frequency bands, ensuring stable signal transmission and improving the communication quality and efficiency.
In radio frequency (RF) circuits, it is a crucial switching component. Due to its low resistance (with a typical value of 0.85Ω at 10mA), it can effectively reduce signal transmission loss; the low capacitance (with a typical value of 0.21pF at 5V) reduces the interference with the signal. It is suitable for circuits such as RF switches, attenuators, and modulators, helping to achieve precise signal control and processing.
In addition, in some miniaturized electronic devices with strict requirements for size and performance, such as Internet of Things (IoT) sensors and wearable devices, the surface-mount design and excellent electrical performance of the SMP1340-040LF enable it to play a key role within a limited space, meeting the devices' needs for high-speed signal processing and low power consumption.

Skyworks Solutions Inc. SMP1340-040LF's Category- RF PIN Diode
PIN diodes are diodes with a near - intrinsic semiconductor region (I - region) between typical p - type and n - type regions. This unique structure endows them with special electrical properties, making them particularly suitable for radio - frequency (RF) applications.
In the RF domain, PIN diodes, especially RF PIN diodes, play a crucial role. Since PIN diodes can control the series RF resistance through forward current, they are highly applicable in active gain control (AGC) and transmit/receive switch applications. In AGC circuits, they can precisely adjust the gain by varying the resistance according to the input signal strength, ensuring stable output levels. For transmit/receive switches, they enable rapid and efficient switching between transmission and reception modes, which is essential for the proper functioning of wireless communication devices.
Skyworks Solutions Inc.'s SMP1340 - 040LF is an exemplary RF PIN diode. It features a fast switching speed, allowing for quick transitions in high - speed RF applications. With a low capacitance of 0.21pF at 5V, it minimizes signal distortion and interference, ensuring high - quality signal processing. Its low resistance, only 0.85Ω at 10mA, effectively reduces power loss during signal transmission. Housed in a low - inductance Green™ SOT - 23 package with a lead inductance of 0.4nH, it not only reduces electromagnetic interference but also enhances product stability. Meeting the RoHs standard, it is an environmentally friendly choice. In summary, the SMP1340 - 040LF is an ideal component for various RF applications, providing reliable performance and excellent electrical characteristics.
