TDA5252XUMA1 RF/IF and RFID

RF Transceiver ICs

The TDA5252XUMA1 is a highly integrated, radio frequency (RF) transceiver integrated circuit (IC) designed for applications in the 470 – 862 MHz and 917 – 923 MHz frequency bands.

Application Field

The TDA5252XUMA1 is perfect for a broad range of wireless applications, including radio remote control, wireless access control systems, alarms, and sensors. It can also be used for low power-exposure and non-exposure devices in the 862 to 902 MHz band. Its small form-factor, large bandwidth, extended temperature range, low power consumption, and sheer ease of integration make it a logical choice for applications requiring a low-cost, high performance device.

Working Principle

The TDA5252XUMA1 is designed to facilitate the RF communication for up to two channels in each of the two frequency bands. It has two D-class channels which can be picked up by an external antenna, thus allowing for bidirectional communication. The first receiving channel operates with 470 – 862 MHz frequency bands, and the second receiving channel operates with 917 – 923 MHz frequency bands. The IC also includes three transmit channels, two in the 470 – 862 MHz band and one in the 917 – 923 MHz band. It is also possible to monitor the signals with an external ADC. The IC features frequency and power control, with up to 16 TX/RX power levels.

The part also complies with the FCC and ETSI low power radio regulations, ensuring that devices using the TDA5252XUMA1 can be used in the 862 to 902 MHz band without going through the FCC certification process. It also has on-chip temperature sensing for the operating life of the device, and an adaptive, built-in DC–DC converter for fast start-up in all supply conditions.

The TDA5252XUMA1 is shipped in an extremely compact 5 x 5 mm package, making it ideal for space-constrained applications.

Conclusion

The TDA5252XUMA1 is a versatile RF transceiver IC that is ideal for a wide variety of wireless applications. It is easy to integrate, features extended temperature range, low power consumption, high bandwidth, and is compliant with the FCC and ETSI low power radio regulations. Its 5x5mm package also ensures that it is suitable for space-constrained applications.
