Evaluation and Demonstration Boards and Kits are important components in electronic and electrical engineering. An example of this type of technology is the LMK61E2EVM, which has a range of applications as well as an interesting working principle.

The practical applications of LMK61E2EVM include its use in a range of scenarios. For instance, it can be used in R&D for prototyping, as well as in production and engineering processes. It can be used in the fields of medical, communication, industrial, consumer, automobile and much more. It is capable of helping with tasks such as characterizing complex circuit board layouts before they are put into production. As well as this, it can be used for testing of the design, functions and operation of digital integrated circuits. Additionally, the technology can be used for EMC evaluation and mobile phone RFPA design.

In terms of its working principle, the LMK61E2EVM is based on an integrated reference design. This is a reference design from the Texas Instruments High Performance RF Single Chip Solution. It uses their LMK61 2E-VM single chip solution that comprises of two separate ICs, which are a Quad 14-bit DAC (Digital Analog Converter) (MCP4725) as well as a integrated RFPA (LMK04816). This single chip solution is able to generate quad DA levels for mobile applications.

Essentially this single chip solution+ ensures the potential customer has the advantage of four analog outputs as well as the ability to integrate both the quad DAC interface and a digital radio frequency (RFPA) into their systems. This has the benefit of providing greater power efficiency for designers as well as reducing the total component count in their designs. This means cost as well as power savings for customers and organisations.

This single chip solution is based upon a 3V3 reference design and provides a range of operating levels. Mainly, it contains a 5V supply PIN for external power supply, a 3V3 supply and a further 12V supply. It is capable of operating from a temperature range between –40°C to +85°C.

This particular IC has a range of features that make it particularly attractive for customers. Firstly, it has a programmable gain amplifier (PGA) that is capable of working from -20dB up to +20dB in 1 dB steps. This is complemented by both flat amplitude response and gain flatness. The device also consists of a wideband harmonic power detector designed for wideband applications. This is backed up by its long-term drift stability, wideband noise floor and the flexibility of four complete bias networks.

The full system includes an on-board phase-locked loop (PLL), and a synthesizer, which is capable of generating a range of frequencies ranging from 10KHz up to 20MHz. As well as this, it also contains a crystal oscillator, as well as a low-noise voltage controlled oscillator (VCO) for frequency agility. This system is also capable of generating precise phase relationships between two signals, which is an important factor for a number of applications.

The LMK61E2EVM is a versatile device, with applications and features that are able to serve a large range of purposes. From prototyping to production, as well as industrial and design tasks, this complete system has proven to be extremely beneficial to customers and organisations in terms of both time and money.
