The MAX7058 UHF transmitter alternatively transmits ASK/OOK data at 315MHz or 390MHz using a single crystal. The MAX7058 has internal tuning capacitors at the output of the power amplifier that can be programmed for matching to the antenna or load. The MAX7058 can transmit at a data rate up to 100kbps NRZ (50kbps Manchester coded). Typical transmitted power into a 50Ω load is +10dBm. The MAX7058 operates from +2.1V to +3.6V and draws under 8.0mA of current. The standby current is less than 1µA at room temperature. A 15MHz crystal is used as the reference for 315MHz and 390MHz operation by selecting synthesizer-divide ratios of 21 and 26, respectively.
The MAX7058 is available in a 4mm × 4mm, 24-pin thin QFN package and is specified to operate in the –40°C to +125°C automotive temperature range.

Evaluation Kit for the MAX7058
Product Detail
The MAX7058 evaluation kit (EV kit) provides a proven design to evaluate the MAX7058 dual-frequency ASK transmitter in a 24-pin TQFN package with an exposed pad. The EV kit enables testing of the device's RF performance and requires no additional support circuitry. The RF output uses a 50Ω matching network and an SMA connector for convenient connection to test equipment. The EV kit comes with a MAX7058ATG+ installed on the EV board.
