Customer Demand

I. Project Background
Chengdu XST Microwave Communication Co., Ltd, as a leader in the field of RF microwave and electromagnetic security, has been committed to technological innovation and product upgrading to meet the ever-changing market demand. And XST, as a leading company in the design and production of microwave electronic components, has provided high-quality and high-performance products for many customers with its profound accumulation in the field of receiver modules and digital receivers. This co-operation aims to combine the advantages of both parties to provide more advanced digital receiver solutions for Chengdu XST Microwave Communication Co., Ltd. and jointly promote the development of digital receiver technology.
II. Implementation Process
From the beginning of the project, XST has maintained close communication and cooperation with Chengdu Xike Microwave Communication Co. We understood the customer's needs and grasped every detail to ensure that the project could be carried out smoothly. With XST's decades of experience in receiver design and manufacturing, we customised a digital receiver for Chengdu Xike with the advantages of high sensitivity, high accuracy, high stability, flexible design and the ability to implement complex functions.
During the project implementation, we focus on the interaction and feedback with customers. At every design node, we have in-depth discussions with the customer to ensure that the design solution can fully meet the customer's actual needs. At the same time, we also provide a series of technical support and training for customers to help them better understand and use our products.
III. Service Support
In order to ensure that customers can get a smooth experience in the process of use, we provide a full range of technical support and after-sales service. In addition, we also provide customers with regular maintenance and repair services to ensure that the digital receivers can run stably for a long time. Our after-sales service team is always on standby, ready to provide customers with emergency assistance and technical advice.

Through this co-operation, we deeply feel the importance of close co-operation with our customers. In the future, we will continue to uphold the concept of ‘customer-centred’ to provide customers with more high-quality and efficient products and services. At the same time, we also look forward to working with more partners to jointly promote the development and innovation of microwave communication technology.

Product Features

20MHz ~ 3.3GHz wideband frequency reception range
Adjustable digital IF bandwidth up to 20MHz
I/Q stream recording to a maximum bandwidth of 500kHz, enabling offline signal processing
Supports demodulation of AM/FM broadcast signals and provides an analogue audio streaming interface.
Signal playback storage makes it possible to reliably monitor, process and locate short-duration signals or disturbances
LAN interface for remote control and data output
Well documented API for system programming or application development.
Low power consumption, light weight and compact size make it ideal for system integration and installation.

Applications

• Slave receivers in integrated systems for channel demodulation and broadband spectrum scanning
• Detection of interfering signals in the radio network, helping the user to quickly eliminate sources of interference
• Monitoring of user-specific radio services and monitoring of a large number of radio services in different scanning modes
• Slave receivers for specialised communication users, which can save baseband data of narrowband channels in real time
• Detection of small transmitters, using the differential spectrum function to detect small radio listening surveillance equipment
