RF Mixers are two-port active or passive devices which employ non-linearities to convert signals between two aspects of a communication system. An RF Mixer is used to convert signal frequencies from transmitters to receivers, to up-convert or down-convert baseband signals to RF signals and vice-versa, as well as to demodulate and modulate signals. The HMC558LC3BTR is an RF mixer with a frequency range of 500 MHz to 5.8 GHz for general purpose applications.

The HMC558LC3BTR is a low cost, low noise, broadband, RF mixer which can be used to implement wide bandwidth communications systems utilizing large frequency separations. The device features a unique adaptive thresholding algorithm that allows the device to adjust the input sensitivity without sacrificing dynamic range, providing maximum flexibility. The device also features an integrated high-linearity, low-noise preamplifier to reduce component count and complexity. In addition, the device is CMOS process-compatible, allowing for cost efficient operation.

The HMC558LC3BTR is designed to work in down-conversion applications. In a down-conversion application, an RF signal is applied to the input port of the device. The RF signal is modulated onto a carrier, and the output consists of the modulated signal and the sum and difference products of the modulation components. The output is then filtered to eliminate unwanted mixing products, and the desired signal is recovered.

The HMC558LC3BTR also features an integrated sputter-on isolation circuitry for maximum isolation between ports. Additionally, the device also features an integrated temperature sensor for controlled temperature compensation. This helps ensure optimum performance and maximum temperature stability.

The HMC558LC3BTR is ideal for a variety of applications, including frequency synthesizers, cellular infrastructure, cellular telephony, broadcast radio systems, satellite receivers, WLAN systems, telecom infrastructure, cable TV network systems, and a variety of other RF systems. The device is also well-suited for use in wireless communication systems such as WiMAX and Wi-Fi.

In summary, the HMC558LC3BTR is a low noise, low-cost, RF mixer designed for use in down-conversion applications. The mixer features unique adaptive thresholding technology and integrated high-linearity, low-noise preamplifier. The device is ideal for a wide range of applications in wireless communication and other RF systems.
