RF mixers, or radio frequency mixers, are two-port devices used in microwave radio designs to mix different RF signals to create new signals. The HMC213AMS8ETR is a high-performance single-balanced activeplus™ RF mixer which combines high-linearity performance with dual-mode ports for frequency doublers, frequency translators, and image rejection mixers. It operates over a wide range of frequencies from 2GHz to 8GHz, has a conversion loss of 10dB and an LO-RF isolation of greater than 30dB. It also includes a amplifier buffer stage to enhance linearity performance and reduce noise figure.

The HMC213AMS8ETR may be used in a variety of applications, such as frequency down conversion mixers, frequency up conversion mixers, image rejection mixers, frequency translators, up converters, and down converters. In down converters, the RF input is mixed with a local oscillator (LO) signal to produce the sum and difference of the two frequency signals. The output signal is the difference between the RF and LO frequencies, and is lower than the original RF signal. The up converter operates in the same way, but the output signal is higher in frequency than the RF signal. Image rejection mixers also function similarly, but the output is the difference between the two signals with the lower frequency signal rejected.

The HMC213AMS8ETR is a well-rounded device and provides excellent performance in a variety of applications. By integrating a differential amplifier at the balun output, the LO-RF port isolation is increased to greater than 30dB, and with the use of a noise pre-filter, the NF is further improved. The on-chip amplifier buffer stage enhances the linearity performance and helps to reduce the conversion loss. The output stage includes variable-gain OIP3 of greater than 22dBm which ensures a good noise figure and wide dynamic gain range.

The HMC213AMS8ETR is suitable for applications that require excellent linearity and high LO-RF port isolation. It is also designed to minimize power consumption and generate only low amounts of heat, making it a desirable choice for integrated systems. The device is housed in an MSOP-8 package and can be mounted on either a commercial evaluation board or a standard surface mount. The HMC213AMS8ETR can be used in a wide variety of wireless communications applications, such as portable radios, radar systems, cell sites, and satellite communications.
