The Tri-band WiFi 7 Omnidirectional Antenna platform offers unmatched signal coverage.

Rapid adoption of 5G technology and IoT devices has driven the demand for high data rate optical modules, especially from data centers for inter- and intra-communication purposes. Increasing the optical module data rate from the current 100Gbps to 400Gbps/800Gbps is an efficient way to upgrade the network infrastructure. PAM4 signal modulation and coherent technology are key for the new high data rate optical module design. To fulfill the tight design requirements of the new PAM4 type optical module, a high frequency, tight stability, low jitter, low power consumption, and small size differential crystal oscillator is very critical. As a leading company in Frequency Control Products, Taitien’s crystal oscillators are being used at the forefront of the optical module industry. Recently, we released a new series of crystal oscillators (OB-U series). Its ultra-low jitter performance (50fs typical, 100fs max), low current consumption, and smaller size (2.5 x 2.0 mm) make it the best fit for PAM4 type optical module designs for data centers, servers, and networking applications.

GNSS-L125-TNC Antennas

GNSS-L125-TNC Antennas achieve pinpoint accuracy with redundancy in positioning, which mitigates errors caused by multipath.

With the arrival of the 5G era, the demand for high-speed transmission is increasing. In the high-frequency and high-energy-consumption environment, the requirements for the frequency stability and accuracy of crystal oscillators are also increasing. In the past, the commonly used IEEE1588 network communication standard used a 25 MHz quartz oscillator, the display used a 27 MHz oscillator, PCIe commonly used 33.333 MHz, and recently, due to the long-term operation of fan less PC systems in high-temperature environments, products with a frequency stability of ±25 ppm or ±50 ppm have gradually been replaced with higher-precision ±10 ppm quartz oscillators to improve signal stability and network quality.
Taitien Electronics has launched a new generation of ±10 ppm high-precision CMOS crystal oscillators, OY-B Type and OX-B Type, to meet the demand between ordinary oscillators and temperature-compensated oscillators, providing a cost-effective high-precision solution.

Quartz crystal is an electronic component that utilizes the piezoelectric effect of quartz to generate high-precision oscillation frequencies. Quartz has become an important component which is widely used in various electronic devices due to its physical characteristics of low temperature coefficient and high Q value. Taitien is one of the few manufacturers who owns its in-house wafer cutting technology. By vertically integrating the production of upstream quartz wafers, wafers’ angles and thicknesses are cut precisely so as to control the material source and quality. Taitien is keenly aware of the mainstream development of electronic products that are light and thin, as well as the demand for high-speed transmission and high-frequency communication. We provide a variety of miniature, low-power consumption, high-precision and wide-temperature quartz crystals to satisfy customers’ diversified needs for quartz components.

• Ultra-small package and ultra-thin of 0.3 mm which is ideally suited for low circuit board height or ultra-small wearable applications

>>High Precision Quartz Crystal Series (High Precision XTAL)

• Excellent power-on characteristics: Since the thermal overshoot of a SC-cut resonator is about 2 orders of magnitude smaller than an AT-cut, the SC-cut crystal oscillator can quickly reach its frequency stability after powering up. In general, the stability can reach 2×10^-9 after powering up for 6 minutes.
• Low aging: The stress effect of the SC-cut resonator is small and the aging caused by stress relaxation is also small. The aging rate can reach 10^-11/d.
• Outstanding short-term frequency stability: After the drive level is increased, the signal-to-noise ratio relative to the white noise is increased, thus the far-end phase noise can be improved. Currently, the highest level can reach -160~-170 dBc/hz.

The Shield Can and Clip range from Harwin is based on the concept of fast assembly and component protection. Designed for use within an existing SMT circuit board layout, these products are a simple and cost-effective method of shielding vulnerable or EMI-radiating board components.

By using a push-action, the removable shield can is held in place with SMT mounted spring clips, so no additional secondary soldering operation is required. All soldering takes place on the clip, at the same time as the rest of the PCB components. This eliminates the risk of heat damage and hot spots (caused by hand soldering) affecting the more expensive components located under the can.

The devices under the can are also now accessible at any time, by simply pulling out the can from the clips. Rework and module replacement can be completed, and the can is simply pushed back into place again.

Shield Cans are available in three different material thicknesses (0.3, 0.2 and 0.15mm) to assist matching to different EMI / RFI characteristics. Clips are supplied in a variety of shapes and sizes for added design flexibility.
