RF mixers are essential devices in the field of wireless communication because they can convert signals between the frequency and the baseband domains. The HMC526LC4 is one RF mixer that is specifically designed to meet the demanding requirements in the digital satellite broadcasting, cable television and wireless data markets. This mixer offers a conversion loss of only 5.7dB, as well as high IIP3 of +24dBm at a typical local oscillator (LO) drive level of 0dBm. It also covers frequencies from 2.4GHz to 2.7GHz, and exhibits excellent linearity.

The HMC526LC4 is based on a double balanced Gilbert cell configuration, which allows it to achieve low conversion loss. It also includes an integrated passive low pass filter which eliminates out-of-band signals from the conversion process. The device’s active solution amplifier feature provides improved linearity and strengthened isolation up to 12dB across the band. Internal matched control lines that can switch between input and output ports allow for continuous signal conversion, and makes the unit suitable for use in frequency hopping systems. The mixer’s low current draw of only 7mA also makes it a great choice for portable and battery-powered applications, such as pagers and satellite phones.

The working principle of the HMC526LC4 is described as follows. It uses a three port mixer in which two serving as ports for input signals while the third port serves as a local oscillator. A local oscillator is used to convert the input signals to the desired output frequency. The mixing process is then carried out, by mixing the input signal with the local oscillator signal to create a difference frequency, which is the output signal. This output signal is then sent to the output port. The mixer also incorporates a low pass filter, which is designed to eliminate unwanted signal components from the frequency conversion process.

The HMC526LC4 is a great choice for both digital satellite broadcasting and cable television. It offers high performance and excellent linearity, and its low current draw makes it ideal for portable and battery-powered applications. Additionally, its internal low pass filter and integrated passive components make it suitable for frequency hopping systems. Overall, the HMC526LC4 is a great mixer that offers high performance for any application on the 2.4GHz to 2.7GHz range.
