RF MixersFrequency mixers are a type of nonlinear circuit, usually providing frequency conversion between input and output signals. Frequency mixers are key components of many communication and radar systems. The particular mixer being considered is the HMC207AS8TR, an active double balanced subharmonic mixer, which performs a variety of operations.The HMC207AS8TR is capable of operating as a down converter, up converter, or modulator. Its differential and single ended RF inputs bring a range of flexibility and performance. The performance of the HMC207AS8TR mixer is further enhanced by using an external strip line balun, which provides superior image rejection and reduction of out of band responses. The HMC207AS8TR has a wide range of operation frequencies – 9.3 – 10.1 GHz in the RF domain, and 8.6 – 9.4 GHz in the LO domain. To give the mixer maximum flexibility, both RF and LO ports are internally DC blocked.As an active double balanced subharmonic mixer, the HMC207AS8TR has a number of advantages over traditional passive mixers. Firstly, it has higher linearity than a passive mixer due to the use of high power, low noise amplifiers. Secondly, it has good image rejection, which is further enhanced by the external balun. Thirdly, it has improved accuracy due to the differential inputs, which are less sensitive to temperature variations. The HMC207AS8TR operates in the same way as all nonlinear circuits by producing a range of frequencies based on the input signal. The output signal is a result of the combining of the input signal with a LO, usually the same frequency as the input signal but at double the power. This process is often referred to as frequency multiplying. The HMC207AS8TR is specifically designed for the 9.3 – 10.1 GHz frequency range, and is optimised for subharmonic mixers.The HMC207AS8TR is suitable for a range of wireless and radar applications, including cell-phone, Wi-Fi, WiMAX and satellite communications, automotive radar systems, and high-speed radio links. It is a highly useful mixer for any application requiring frequency shifting over a wide range of frequencies. Overall, the HMC207AS8TR is a highly capable double balanced subharmonic mixer. Its high power, low noise amplifiers, and differential inputs give it superior performance over traditional passive mixers. It is optimised for the subharmonic frequencies, and is suitable for a range of wireless and radar applications. As a result, it is an ideal choice for any application requiring frequency shifting.
