Design of RF Transceiver Circuit Based on TRF6900 MCU
This article introduces the structure, principle, characteristics and application circuit of TRF6900. TRF6900 is a single-chip radio frequency transceiver chip, which integrates a complete transmitting circuit and receiving circuit. This kind of transceiver also has FM/FSK modulation mode and adopts three-wire serial interface, so it can be easily connected with the microcontroller. It is suitable for computer telemetry and remote control system, handheld battery-powered operating system instrumentation equipment and safety protection system.
The Application of two-way radio frequency transceiver NCV53480 in the next generation of RK
This article introduces the structure principle of NCV53480. Its biggest advantage is single-chip high frequency transceiver, Rx and Tx can directly share the same impedance matching network and antenna. And high-frequency remote wake-up can be realized through sniff mode, while having lower standby power consumption. Thereby reducing the complexity and cost of system design, and realizing a simpler two-way RKE system.
Improve RF transceiver design performance with differential interface
This article mainly discusses the three main advantages of differential interface, and discusses the interface solutions in three situations: ZIF receiver, superheterodyne receiver and transmitter. These three architectures are widely used in remote radio units (RRU), digital repeaters and other wireless test instruments.
Highly integrated national standard ETC RF transceiver application system
Compared with the OBU solution implemented by the application of discrete components, the BK5822 requires only a small number of external components, which saves the PCB area and the cost of peripheral components to the greatest extent, shortens the research and development cycle, and improves the yield of product production. The BK5822 integrates OBU. All the required RF function modules make the design easier, the development and debugging easier, and the mass-produced OBU products have more stable performance.
