TDA5210 - Infineon Technologies

TDA5210 ASK/FSK Single Conversion Receiver

The IC is a very low power consump- Package tion single chip FSK/ASK Superheterodyne Receiver (SHR) for the frequency bands 810 to 870 MHz and 400 to 440 MHz that is pin compatible with the ASK Receiver TDA5200. The IC offers a high level of integration and needs only a few external components. The device contains a low noise amplifier (LNA), a double balanc.
