380- to-450-MHz Transmitter Chip 31262

With clock output in ultra-small QFN package

The TH72016 transmitter works in virtually any FSK, ASK, or FM system in the 380 to 450 MHz unlicensed Industrial-Scientific-Medical (ISM) and Short-Range-Devices (SRD) frequency bands. Its extended operating temperature range of -40 to +125C and clock output to drive a microcontroller make it ideal for automotive applications such as Tire Pressure Monitoring Sytems (TPMS) or Remote Keyless Entry (RKE) that require enhanced data timing. The TH72016 comes in a space-saving 10-pin Quad Flat No-lead (QFN) package with a footprint of only 3 x 3 mm. The TH72016 IC accepts battery voltages from 1.9 to 5.5 V. Power consumption ranges from 3.5 to 12.8 mA depending on the frequency and power setting. In standby mode the current consumption is below 50 nA. The programmable RF transmit power range between -12 to 10 dBm allows the designer to adapt to his RF power requirements. Melexis http://rbi.ims.ca/4912-548
