The SI4060-C2A-GMR from Silicon Labs is a low power, 10 dBm (10 mW) RF-transmitter that can easily be included in wireless solutions. This transmitter is important part of wireless platforms such as Zigbee, Bluetooth, Wifi and other solutions which require medium to long range transmissions. It is ideal for systems with limited availability for power as it only requires as little as 9V of operating power. The SI4060 has been designed to provide consistent performance over a wide range of operating temperatures, which makes it suitable for automotive and industrial applications.

The SI4060-C2A-GMR features a crystal oscillator (COP) circuit that operates on 32 MHz or 40 MHz. This oscillator is necessary to generate the frequency of the transmission signal. It is designed to accurately generate the frequency of the transmission signal, which allows for reliable and consistent transmissions over the designed frequency range of 2.400 to 2.4835 GHz. This range covers the vast majority of wireless frequencies in use globally.

The RF portion of the transmitter utilizes a quadrature modulator and power amplifier to achieve the required output power. The modulator is integral to the direct-conversion architecture used by the SI4060-C2A-GMR, and is the result of an optimized combination of low-noise and functionality. This modulator utilizes four I and Q signals, which represent quadrature amplitude modulation (QAM) type modulation schemes. The modulator then converts these signals into a digital signal, which is then sent to the power amplifier, increasing the power of the transmission signal.

The power amplifier in the SI4060-C2A-GMR is designed to support up to 10 dBm of output power, which is ideal for short and medium range transmission applications. This amplifier also has two built-in digital gain control registers to adjust the output power, allowing designers to tweak the power level as required. The amplifier also has a transmitter output enable/disable control that can be used to turn the transmitter on/off as required.

The SI4060-C2A-GMR is an ideal solution for any application that requires reliable low-power transmissions, such as medical and industrial applications. Its low power requirements allow it to be included in wireless solutions, while its wide range of operating frequencies makes it suitable for global deployments. The direct-conversion architecture and integrated devices make it a cost-effective solution for wireless applications.
