TDA5212 ASK/FSK 915MHz Single Conversion Receiver

The IC is a very low power consump- Package tion single chip FSK/ASK Superheterodyne Receiver (SHR) for the receive frequency range between 902 and 928 MHz that is pin compatible to the ASK Receiver TDA5202. 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 balanced .
