RF Transceiver Modules play an important role in modern radio frequency systems, allowing data transmission, control, and remote communication. The 27264 is a popular RF Transceiver Module, suitable for a variety of Low Power applications.

Overview. The 27264 is an integrated, low-power, surface-mountable transmitter and receiver module that operates in the ISM (Industrial, Scientific, and Medical) band at frequencies from 2400 to 2485 MHz. The module is designed for short-range wireless applications with enhanced data rate and modulation capabilities.

Features. The 27264 is a highly integrated module that features a low power consumption of less than 21 mA for transmission and 11 mA for reception. It features a 16-pin QFN package with an integrated antenna which allows good RF shielding and low insertion loss (<1 dB) for improved sensitivity. The module also offers good receiver sensitivity of -90 dBm at 9.6 kbps data rate. Furthermore, it has an improved output power of +12 dBm, and is capable of achieving up to 16 Mbps gross data rate.

Application fields. The 27264 RF Transceiver Module is ideal for a variety of short-range wireless communication applications, including wireless sensor networks, home automation, and automotive access systems, among others. It can be used in various security and alarm systems, medical devices, and industrial control systems, as well as in data communication require low-power and long-ranging communication.

Working Principle. The 27264 transmits data by modulating an input signal using Frequency Shift Keying (FSK). It modulates the signal depending on the data rate and modulation parameters which are programmed using a Serial Peripheral Interface (SPI). The output of the modulated signal is then amplified and transmitted through the antenna. At the receiver side, the transmitted signal is received by the antenna, demodulated, and digital data is recovered. This data is then available for applications to use.

The 27264 RF Transceiver Module is a powerful tool for modern wireless communication applications, offering good sensitivity, low power consumption, and an easy to use interface. It is also cost-effective and has a small form factor, making it an ideal choice for a variety of applications.
