This frequency synthesizer offers a wide range of applications in various industries, scientific research and defense systems. This article will discuss the application field and working principle of the FZTYP7E7EAAF250.

Application Field

The FZTYP7E7EAAF250 frequency synthesizer is suitable for a wide range of applications. It can be used in radio and television transmission, mobile communication systems, satellite communication systems, radar navigation systems, and medical systems. The wide frequency range (from 14MHz to 7GHz), excellent harmonic suppression (above -82dBc/Hz @ 100 kHz offset), and phase noise performance (below -108 dBc/Hz @ 100Khz offset) make this frequency synthesizer suitable for a wide range of applications.

The FZTYP7E7EAAF250 has first-class parameters such as phase-locked loop (PLL), frequency agility, frequency hopping, frequency stabilization, dynamic frequency adjust range, polynomial frequency synthesis, harmonic suppression, and wide frequency range. It also features excellent output spectrum purity, linearity, and stability. Moreover, the synthesizer enables high speed ramping or settling in few microseconds.

Working Principle

The FZTYP7E7EAAF250 frequency synthesizer utilizes a combination of digital and analog technique to achieve wide frequency coverage, excellent harmonic suppression, and low phase noise. The signal path scheme of the synthesizer is shown in figure 1:

As shown in figure 1, the FZTYP7E7EAAF250 comprises a digitally controlled oscillator (DCO) and a PLL loop. The DCO generates a reference waveform of a frequency proportional to the input digital code. The PLL loop compares the phase and frequency of the generated reference waveform with that of the external reference signal and adjusts the amplitude of the DCO output signal to make them identical. The frequency synthesizer can then deliver a waveform with a desired frequency, excellent harmonic suppression, and excellent phase noise performance.

Furthermore, the FZTYP7E7EAAF 250 offers an integrated frequency stabilization system to optimize frequency versus temperature. It also has features like built-in frequency agility, and polynomial frequency synthesis that enable multiple waveforms of different frequencies and phases to be generated for relaxed phase noise and low cross-correlation characteristics.

Conclusion

The FZTYP7E7EAAF250 frequency synthesizer is an extremely powerful and versatile device. It has wide range of applications in various industries, scientific research, and defense systems. This frequency synthesizer features excellent harmonic suppression, wide frequency range, wide frequency adjust range, dynamic frequency adjust range, and polynomial frequency synthesis. The FZTYP7E7EAAF250 is also equipped with a frequency stabilization system to maintain frequency stability even at high temperatures. The article has discussed the application field and working principle of the FZTYP7E7EAAF250 frequency synthesizer.
