RF mixers are essential devices used to combine or mix two signals, one of which is at the radio frequency and the other at the intermediate frequency or the local frequency. RF mixers are used in many applications such as radio receivers, transmitters, spectrum analyzers, vector network analyzers, frequency synthesis and test instrumentation. HMC521LC4 is a RF Mixer with an internal active balun. It is currently being used in high performance as well as low cost applications.

The HMC521LC4 is a sub-harmonic mixer designed to operate over the 2 to 3 GHz range with an RF/LO frequency ratio of 1:2, and 12 dB of conversion loss. The mixer’s drain voltage (Vd) is 3.3 V and its drain current is typically 8 mA. The mixer offers a high dynamic range due to the low noise figure and LO/IF leakage suppression of up to 35 dB. The mixer also features a high RF input third-order intercept point of + 25 dBm.

The HMC521LC4 is a balanced active mixer that utilizes an RF/LO balun, an RF transformer and a differential amplifier. The RF balun is used to match the single-ended input signal to a differential one. The RF transformer is then used to convert the differential signal to a single-ended signal. The resulting single-ended signal is then amplified in an amplifier stage and passed through the LO balun. The output of the LO balun is a differential signal which is then amplified by the differential amplifier to obtain the output.

The HMC521LC4 is well suited for wideband applications such as wireless, telecommunications, test instrumentation, and signal processing. It is used in applications such as Wi-Fi 802.11 b/g/n, cellular communication systems, wireless peripherals, Bluetooth, GSM, EDGE, EV-DO, and WCDMA devices. The device is also suitable for receivers, transmitters, and transceivers used in the 2 to 3 GHz ISM band. Other applications include point-to-multipoint systems, mobile devices, and digital TV receivers.

Overall, the HMC521LC4 is a high performance and cost-effective mixer. Its integrated active balun and its wide dynamic range make it suitable for a variety of applications. It performs well in applications such as Wi-Fi, GSM, EDGE, WCDMA and Bluetooth, among other applications. It also offers excellent noise suppression and high RF input third-order intercept point. The HMC521LC4 provides an effective solution for applications requiring RF mixing technology.
