CMT2189C

The CMT2189C devices are fully integrated, highly flexible, high performance, SoC (G)FSK/OOK transmitters with 240 to 960 MHz wireless applications.

Description

 The CMT2189C devices are fully integrated, highly flexible, high performance, SoC (G)FSK/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 CMT2189C 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 PA output can be either single-ended or differential.The device operates from 2.0 V to 3.6 V. Its low power design enables superior operation life for battery powered application. The CMT2189C transmitter together with CMOSTEK NextGenRF TM receiver enables a highly flexible, low cost RF link.
