RF mixers are commonly used electronic components used to multiply two signals and generate an output signal of two separate frequencies. The HMC485MS8GETR is an example of such a mixer. In this article, we’ll examine the application fields and working principle of the HMC485MS8GETR.

The HMC485MS8GETR is an 8GHz passive mixer designed for use in a wide range of radio applications. It is capable of converting signals in the frequency range of 1.1 to 10GHz and is ideal for use in satellite communication systems and mobile communication systems.

The HMC485MS8GETR is a mixer based on a Gilbert cell topology. The Gilbert cell is a type of multistage amplifier which operates using differential pairs. The figure below shows the schematic of a Gilbert cell. The two inputs to the Gilbert cell are typically differential pairs.

In a Gilbert cell topology, the two input signals are multiplied to generate an output voltage. The two signals are coupled to an inverting amplifier which is then combined with the non-inverting amplifier. The output signal is then passed through a low-pass filter to remove the high-frequency components.

The HMC485MS8GETR also features a low loss hybrid balun which is optimized for use in 8GHz applications. The balun eliminates the need for external components in the mixer circuit, leading to a lower cost and a more compact design. The balun is also optimized for low-level input signals meaning that it can handle smaller signals than other mixers.

The HMC485MS8GETR is ideal for use in a wide range of communication systems. It is designed to be used in applications such as satellite communication systems, cellular communication systems, and RFID systems. It also can be used in radar systems and medical imaging systems.

In conclusion, the HMC485MS8GETR is an 8GHz passive mixer with a Gilbert cell topology which is ideal for a wide range of applications. Its low loss hybrid balun allows it to handle low-level signals, making it an ideal choice for applications such as satellite communication systems and cellular communication systems.
