• Manufacturer Part Number: TDA5252G2
• Description: ASK/FSK 915MHz Wireless Transceiver
• Manufacturer: INFINEON [Infineon Technologies AG]

4.1.3
AC/DC characteristics involve the spread of values guaranteed within the specified voltage and
ambient temperature range. Typical characteristics are the median of the production. The device
performance paramter marked with x are not part of the production test, but were either verified by
design or measured in an Infineon Evalboard as described in Section 4-2.
