RF Evaluation and Development Kits, Boards are essential tools used in a variety of industries for prototyping, testing and refining a wide range of technological projects. One such tool is the 108648-HMC733LC4B, which is capable of providing a comprehensive evaluation of RF performance in a multiband system.

Overview:

The 108648-HMC733LC4B evaluation board is developed for designers to evaluate the performance of the HMC733LC4B LNA. It should not be used for any other purpose. This kit includes two daughter cards which can be used to characterize the performance of the HMC733LD4B in two systems simultaneously. In addition, this board provides a simple foundation for further prototyping using the HMC733LD4B in various applications. This evaluation board takes power from the 3.3V supply and offers two distinct outputs equalized and un-equalized.

Application Field:

This evaluation board is designed primarily for use in prototyping multi-band RF systems. It is especially suitable for applications such as wireless communications, radio frequency identification (RFID), sensor networks and military radios. The board is also capable of providing measurements such as gain, noise figure and input/output match in order to assess the performance of the multi-band RF system.

Working Principle:

The HMC733LC4B LNA evaluation board operates according to an open loop architecture. It consists of a two-stage amplifier with a dc-coupled output stage. The first stage consists of a low-noise transconductance stage with a gain of 19.5dB and a noise figure of less than 1.8dB. The second stage contains two common source MOSFETs and provides a further gain of 16.3dB. DC bias current is supplied from a regulated 3.3V supply, while the supply voltage for the LNA input is generated from an on-board shunt regulator. To ensure optimal performance, the board has also been designed with a negative feedback circuit.

Conclusion:

The 108648-HMC733LC4B evaluation board is an extremely useful tool for designers and engineers working on multi-band RF systems. It is capable of providing comprehensive evaluation of the performance of the HMC733LC4B LNA and allows designers to quickly prototype and refine their designs. Furthermore, the board includes a negative feedback circuit to ensure stable system performance while the two-stage amplifier provides a gain of up to 35.8dB.
