AD9959 High Speed DDS Module 4-Channel Direct Digital Frequency Synthesizer with 4PCS BNC-SMA RF Cables

Description:
- The AD9959 consists of four direct digital frequency synthesizer (DDS) cores, each of which can provide independent frequency, phase, and amplitude control (i.e. adjustable). Each channel is equipped with an independent high-speed 10 bit DAC, a dedicated 32-bit frequency control word, a 14 bit phase offset, and a 10 bit output proportional multiplier. Can be used to correct imbalances between signals caused by analog processing such as filtering, amplification, or PCB layout mismatches. Due to the fact that all channels share a common system clock, they have inherent synchronization and support synchronization across multiple devices.
- AD9959 can perform up to 16 orders of frequency, phase, or amplitude modulation (FSK, PSK, ASK). Modulation can be performed by applying data to the mode pin. In addition, AD9959 also supports linear frequency, amplitude, or phase scanning suitable for applications such as radar and instrumentation.

Advantages:
- Compared to other modules, the sine wave output amplitude is higher and the driving force is stronger.
- Each channel is equipped with a high-order low-pass filter design, ensuring waveform phase noise performance, harmonic performance, and high linear waveform flatness performance.
- Provide AD9959 with rich functional programs that can output ASK, FSK, PSK, etc.
- Compared to other modules, each signal on the board is equipped with an RF transformer, and when four channels are output simultaneously, they do not interfere with each other.
