*The traditional scheme of using discrete components as walkie talkie has long been far from meeting the manufacturer's requirements for cost and volume; Especially in the rapid completion of walkie talkie development.

Therefore, in response to market demand, the company independently developed and designed a single-chip interphone solution. Integrate all traditional discrete component schemes into a small module. The module fully integrates all functions of the walkie talkie, with built-in high-performance RF transceiver chip, microprocessor (MCU) Radio frequency power amplifier (PA), etc. the module has the advantages of small volume, high integration, stable performance, flexible application, and meets the interphone standards of most countries in the world. It is widely used in any mobile handheld products, such as three defense mobile phones, handheld interphones, industrial wireless interphones, paging systems, smart homes, industrial data acquisition and other fields.

Welcome to call and write for consultation. We can provide sample testing and perfect technical support to meet your needs to quickly complete the product design.
