Celebrating the 10th Anniversary,Jingxin Entering the Development of Next Decade

Jingxin was already 10 years old on 1st, Mar 2022, which started up as a small business in a tiny apartment, now it turns out to be an established manufacturer of RF microwave components. Jingxin was founded by Mr. Chao Yang in 2012. From here, the business grew up quickly and gradually expanded... Read More

The importance of dB for RF design

In the face of a project indicator of RF design, one of the most common words is “dB”. For an RF engineer, dB is sometimes as familiar as its name. dB is a logarithmic unit that provides a convenient way to express ratios, such as the ratio between an input signal and an output signal. Since dB i... Read More

LoRa VS LoRaWan

LoRa is short for Long Range. It is a low-distance, distance-distance close-contact technology. It is a kind of method, whose biggest feature is the longer distance of wireless transmission in the same series (GF, FSK, etc.) spread farther, the problem of measuring distance and distance coexisti...

The utility model has a simple structure and uses a low intermodulation... Read More

5G Technology Advantages

It was informed by China Ministry of Industry and Information Technology:  China has opened 1.425 million 5G base stations, and this year will promote the large-scale development of 5G applications in 2022. it sounds like 5G really steps into our real life, so why do we need to develop 5G? 1. Cha... Read More

Passive intermodulation (PIM) effect in base stations

Active devices are known to have nonlinear effects on the system. A variety of techniques have been developed to improve the performance of such devices during the design and operation phases. It is easy to overlook that passive device can also introduce nonlinear effects that, while sometimes r... Read More

What is RF attenuator ?

The Attenuator is an electronic component that is widely used in electronic equipment, and its main function is to provide attenuation. It is an energy-consuming element, which turns into heat after power consumption. Its main purposes are: (1) Adjust the size of the signal in the circuit; (2) I... Read More

Connection between RF Combiner and Hybrid Coupler

The different frequency band combiner refers to the signal power synthesis of two different frequency bands. For example, RF Combiner CDMA and GSM power synthesis; CDMA/GSM and DCS power synthesis. Due to the large frequency separation of the two signals, RF Combiner the two frequency signals can... Read More

Importance of RF filters

Why RF filters are becoming more important？ The rapid growth of mobile wireless data and 4G LTE networks has led to a growing demand for new bands and for carrier aggregation to combine bands to accommodate wireless traffic. The 3G network uses only about five bands, and LTE networks now use mor... Read More
