HMC675LP3E

HMC675LP3E is a linear-comparator product developed by Analeka Corporation. It is a high-performance, low-cost RF analog driver that provides excellent low noise performance and flat gain up to 3GHz. The HMC675LP3E is a highly integrated device that includes 4 independent linear-comparator channels, a digitally programmable gain controller, and reference current generator. It provides the user with a wide range of applications for signal conditioning and RF system design. In this article, we will discuss the applications and working principle of the HMC675LP3E.

Applications

The HMC675LP3E can be used in a variety of applications in signal conditioning and RF system design. It is well suited for use in high-performance signal switching, filtering and sampling applications. At the system level, it can be used for a wide range of Gain Control and Amplification solutions, as well as for filter select and RF synthesizer applications. It is also well suited for incorporation into Digital Pre-Distortion and Wide Bandgap Amplifiers.

Working Principle

The HMC675LP3E is based on a dual 4-way linear-comparator architecture. It consists of a core comparator, two independent linear-comparator channels, a gain controller and a reference current generator. The core comparator is a four-wide differential comparator with speed and linearity control. The same control signals are used to control the speed and linearity of each of the linear-comparator channels. The gain controller is a digital potentiometer with a gain range of 3dB to 30dB with 0.5dB steps. This allows the user to tailor the gain of the HMC675LP3E to his specific application requirements. The reference current generator provides a regulated current of up to 20µA for the linear-comparator channels.

The HMC675LP3E uses an advanced voltage-controlled gain tuning scheme. This scheme was developed to provide maximum linearity and high dynamic range. The user can program the gain of the HMC675LP3E using the gain controller. The gain is controlled by varying the reference voltage of the comparator circuits over a range of 3dB to 30dB with 0.5dB steps. The internal current generators allow the user to control the speed and linearity of the core comparator, as well as the linear-comparator channels. This gives the user precise control over the linearity and gain of the HMC675LP3E.

The HMC675LP3E is a versatile linear-comparator product designed to meet the demands of high-performance signal conditioning and RF system design applications. It provides excellent low noise performance and flat gain up to 3GHz. The integrated gain controller and reference current generator allow the user to tailor the gain of the HMC675LP3E to his specific application requirements. This product is well suited for a wide range of applications in signal conditioning, RF system design and Gain Control and Amplification solutions.
