RF mixers are electronic devices used to mix the electrical power of two or more RF signals, producing an output signal containing the sum and difference frequencies of the two input signals. The SKY73082-11 is a wideband RF mixer from Skyworks, Inc. that is capable of operating from 50MHz up to 1.5GHz. It features a high linearity (IIP3) of 30dBm and low noise figure of 18dB. It is suitable for a wide range of applications, including direct conversion receivers, transceivers, multi-standard designs, vector modulation, and other applications requiring wide bandwidth and high performance.

The SKY73082-11 is designed primarily for current-mode operation. In this mode, it works as an RF switch between received and transmit paths. By controlling a low-power current into the device, it will allow the signal to pass either from the antenna to receiver, or from the transmitter to the antenna. This design eliminates the need for expensive high power switches and relay components.

When used for mixing, the SKY73082-11 produces an output signal at the sum and difference frequency of two input signals. This can be used to convert higher frequencies to bands that can be processed on conventional electronics. The current-mode high linearity design ensures that there is minimal harmonic distortion, allowing for higher signal fidelity in applications such as direct conversion receivers and transceivers.

The SKY73082-11 also has significant advantages in multi-standard designs and multi-mode applications. Its wide RF bandwidth enables designers to more easily incorporate multiple signal standards (e.g. GSM, LTE, WCDMA, etc.) without having to redesign the RF circuits. It also allows the device to more easily be used in multi-mode systems, such as smartphones, where a different communication system must be used for each type of communication.

Another application for the SKY73082-11 is vector modulation. Vector modulation is a type of digital modulation which allows for the optimization of signal power between channels. By using a vector modulator in conjunction with the SKY73082-11, designers can create systems that are more efficient at transmitting information over a limited frequency range.

The SKY73082-11 from Skyworks, Inc. is an excellent and versatile RF mixer suitable for a wide variety of applications. Its wide RF bandwidth and high linearity enable it to be used for direct conversion receivers, transceivers, multi-standard designs, vector modulation, and many other multi-mode applications. Its current-mode design negates the need for expensive high power switches and relay components, which makes it very cost effective.
