4G test white card (LTE test white card)

Product Introduction

  LTE test card, 4G test card, lte-fdd card, lte-tdd card, GSM test card, CDMA test card, UIM test card, ruim test card, WCDMA mobile phone test card, TD-SCDMA test card, CDMA2000 test card, mobile phone test card (also known as white card), signal test used in communication industry production (LTE (long term evolution) is the long-term evolution of UMTS technical standards formulated by 3GPP organization, It was officially approved and launched at the 3GPP TSG ran#26 meeting in Toronto in December 2004. The LTE system introduces key transmission technologies such as OFDM and multi antenna MIMO, which significantly increases the spectral efficiency and data transmission rate (the peak rate can reach uplink 50mbit/s and downlink 100mbit/s), and supports a variety of bandwidth allocation: 1.4mhz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz. The spectrum allocation is more flexible, and the system capacity and coverage are significantly improved. LTE wireless network architecture is more flat, which reduces the system delay, network construction cost and maintenance cost. The LTE system supports interoperability with other 3GPP systems. Fdd-lte has become the 4G standard with the widest range of countries and regions and the richest variety of terminals in the world.). It is commonly used in LTE mobile phones, 4G mobile phones, FDD mobile phones, GSM mobile phones, UIM mobile phones, ruim mobile phones, CDMA2000 mobile phones, and carries out non-interference comprehensive tests on mobile phones with the help of comprehensive testers and self built networks; In the production of mobile phones, we need to test the relevant signals of the finished products, but we need to carry out large-scale screening, which requires more human and material resources and testing time, making the production process complicated and the cost increased. The test card can realize the only path from the signal to the instrument to the mobile phone, making the test environment more concise and solving this complicated problem well. The test card can be used for coupling test, bit error rate test, complete VCC and rstb, and can be used for terminal and integrated tester testing.
  

Applicable to Agilent, Anli, rod Schwartz, Galaxy bright spot, agilent8960, Rohde & Schwarz, sunlight, CMU200, cmw500, cmu55, E5515C, e8285a, mt8820a, NOISEKEN, fluke, Tektronic, advantes and other foreign and domestic test instruments, as well as the self built networks of mobile phone manufacturers or operators.


The LTE test card, 4G test card, lte-fdd card, lte-tdd card, test card, GSM test card, CDMA test card, UIM test card, ruim test card, WCDMA mobile phone test card, TD-SCDMA test card, CDMA2000 test card and mobile phone test card of our company adopt special chips produced by internationally famous semiconductor manufacturers, 3v/5v compatible, 5-6 contact compatible design, suitable for all mobile phones Equipped with a special cos system, it fully complies with the specifications of 4G mobile phones, 3G pair mobile phones, 2G mobile phones, etc. our test card has a special semiconductor silicon lining to ensure that the card can withstand a pressure of 10 Newtons / square meter. (GSM standard is 4 Newtons / square meter) it is suitable for industrial production lines. It adopts ultra long-life EEPROM to ensure that the number of reads and writes is more than 100000. (the 3G standard only requires 30000 times. According to the measurement requirements of the general production line, the reading and writing times of each mobile phone is 10 times, and 10000 mobile phones can be measured.), The patented chip protective layer ensures the card security and prevents electronic attacks. Special card coating with voltage resistance above 6.5V, antistatic (ESD), waterproof (48 hour immersion test) special card body material (ABS mixed with high temperature PVC), high temperature resistance, 45 degrees can work normally for more than 4 hours. 75 degree temperature impact test

 

Our products are authorized by the national integrated circuit card registration center to use imported Samsung, Hitachi, Philips and other chips [scope of authorization: s3c89k8 (ks88c92008) s3xc9xx IC card chip series with contacts]. The physical properties, chemical resistance and contact electrical properties of all tested smart cards have passed the inspection of the national computer quality supervision and inspection center and the IC card quality supervision and inspection center of the Ministry of information industry, with authoritative quality assurance.
