Description

 The CMT2189B devices are fully integrated, highly flexible,high performance, SoC OOK transmitters with embedded RISC microcontroller core for various 240 to 960 MHz wireless applications. They are part of the CMOSTEK NextGenRF TM family, which includes a complete line of transmitters, receivers and transceivers. The CMT2189B uses a 1-pin crystal oscillator circuit with the required crystal load capacitance integrated on-chip to minimize the BOM counts. The device can deliver up to +13 dBm output power and the single-ended PA output. The device operates from 2.0 V to 3.6 V. Its low power design enables superior operation life for battery powered application. The CMT2189B  transmitter  together  with  CMOSTEK NextGenRF TM receiver enables a highly flexible, low cost RF link.
