RF mixers are devices used to mix RF signals with incoming RF frequencies. They are commonly used in radio frequency (RF) transceivers, modems and transmitters. BGX7220HN/1,518 is a type of RF mixer, which are usually employed in communication systems for down-converting or up-converting incoming RF frequencies as needed in order for them to be received or transmitted.

BGX7220HN/1,518 is an integrated RF mixer package that supports the dual signal of SIF and audio. The SIF function is enabled by its integrated Integrated Adaptive Sub-channel Selector (IASS) which senses the incoming signal and uses the appropriate SIF output line to generate the output audio signal. Accompanying the SIF function, the mixer also provides a variable audio output level adjustment. The BGX7220HN/1,518 is an ideal choice for radio applications intending to have all these integrated functions.

The working principle of the BGX7220HN/1,518 RF mixer is based on the mixing between two different frequencies applying in the same circuit. Firstly, the incoming frequency signal is multisourced and distributed in the various components of the mixer. Next, the mixer amplifies both the main and sub-frequencies signals present in the incoming signal using dual input hybrid circuits. Then, each of the amplified signals is subjected to a mixing process, and as a result, two new frequencies are created, one being the original frequency, and the other the down- or up-converted frequency.

The mixers are designed to deliver high quality mixed frequencies signals to the respective output devices. In terms of linearity, the mixers offer excellent intermodulation distortion (IMD) figures, and they also provide wide dynamic range performance due to the inclusion of high isolation amplifiers in their design.

BGX7220HN/1,518 is a RF mixer typically used for applications in set-top boxes, digital TV/Radio tuners and digital audio players. The mixer offers a wide range of features such as Automatic Gain Control (AGC), and multiple RF input ports. As for applications, the BGX7220HN/1,518 RF mixer can be used for SIF transmission to encode data transmission for radio broadcast, as well as reception of broadband cable signals, covering a wide band range between 5 MHz and 1500 MHz with excellent gain linearity.

BGX7220HN/1,518 RF mixer is widely used in broadcasting and telecommunications applications. They offer superior features such as AGC, wide dynamic range performance, high output level accuracy, low interference, and adjustable gain. Moreover, such mixers have extensive multi-media capabilities, providing support for digital audio, video and signals from multiple sources.

In conclusion, BGX7220HN/1,518 RF mixers have become a very popular choice for radio frequency applications because of their increased flexibility and superior performance, and are widely used in both consumer and industrial applications such as set top boxes, digital radio and television, and digital audio players.
