The TRF4400 is a fully integrated single-chip RF transmitter for the 433 MHz ISM band. It features a 24-bit direct digital synthesizer (DDS) with 11-bit DAC, on-chip VCO and PLL, and requires minimal external components. The device operates from 2.2 V to 3.6 V and is designed for low power consumption. It supports FM/FSK modulation and provides two fully-programmable operation modes for fast switching. The transmitter includes a power amplifier with typical output power of 7 dBm and can be interfaced to a baseband processor such as the TI MSP430 via a flexible serial interface.
