RF Micro Devices is offering a 5.8GHz transmitter to comply with China's electronic toll collection (ETC) standard, designated GB/T 20851.1-2007.

The ML5830 is a low-power, amplitude shift key (ASK) and frequency shift key (FSK) transmitter. It incorporates a microcontroller to facilitate self-alignment of the VCO, filtering and phase locked loop (PLL) detection and control.

The ML5830 integrates an up-conversion mixer, a buffer/pre-driver amplifier and an ASK modulator capable of producing a typical output power of +4dBm.

The FSK mode provides digitally selectable data rates of 1 and 2Mbit/s. It also incorporates a fully integrated fractional-N synthesizer, a voltage controlled oscillator (VCO) and the necessary filtering to digitally switch to a higher power, higher data rate FSK modulation mode.
