RF Evaluation and Development Kits, Boards have been developed to enable engineers to easily study, test and develop various radio-frequency (RF) systems. The DC1646A is just one of these kits, specifically designed to allow for quick development and evaluation of discrete component level, high Q-circuit designs.

The DC1646A is a complete single-cavity continuous-wave (CW) source solution. The board utilizes an internal power supply, eliminating the need for an external power source. It can produce a frequency range from 1.6 to 6000 MHz with a 3 dB bandwidth of 20 kHz. The board includes an internal thermoelectric cooler (TEC), power-up protection, and high-output power levels. A low-noise amplifier (LNA) and variable attenuator (VA) are also included to enable more precise control of the RF signal levels.

The DC1646A application field is mainly used in cellular base-station support equipment, in particular wireless networks such as 3G/4G, WiFi, WiMAX, GSM/EDGE, GPS, and other high-frequency designs. It can also be useful in telecommunications, automotive systems, and test and measurement applications.

The working principle of the DC1646A is based on radio wave interaction. This involves creating electromagnetic waves at various frequencies, which are then transmitted into the air or another medium. The signal then passes through the environment, propagating until it is absorbed by another medium, such as a receiver. The kit achieves this by modulating the signal using one of the following methods: frequency modulation (FM); phase modulation (PM); pulse modulation; digital modulation (e.g. binary phase shift keying); or amplitude modulation (AM).

The DC1646A features a built-in generator to allow for frequency changes without adjustments to the board. This generator can be used to produce various Q-amplitudes, as well as harmonics, to adjust the output. Additionally, the DC1646A includes an adjustable delay line, allowing for phase-shift adjustment of the signal for more precise control. The built-in RF switch allows engineers to quickly forward and reverse the RF signal for evaluation.

The DC1646A is an economical and efficient solution for RF evaluation and development that offers an efficient and precise approach to RF testing. With its wide frequency range, low-noise design, and adjustable delay line, it can handle a variety of applications. This makes it a great choice for engineers looking to quickly test and develop discrete component RF designs.
