The Phase-Locked Loop Frequency Translator (275PGILFT) is a type of device used in telecommunications, broadcasting, and other applications to transmit baseband signals from one frequency to another. It translates from a lower frequency (LO) to a higher frequency (IF). The 275PGILFT is an advanced development of the classic PLL (Phase-Locked Loop) frequency translator. It is suitable for use in applications such as satellite communication (DVB-S, DVB-S2, DVB-S3, etc.), fixed wireless access, point-to-point radio, VSAT, cable, cellular networks, and Digital Video Broadcasting Terrestrial (DVB-T/T2/T3). The 275PGILFT provides a very high level of frequency translation performance, with extremely low phase noise and excellent linearity.

The basic working principle of a 275PGILFT is simple. An input signal is provided to its local oscillator (LO) input. Once the LO is locked to the input signal, the 275PGILFT frequency translates the input signal to a higher frequency (IF) by frequency multiplying the baseband signal. The phase lock loop (PLL) circuit in the 271PGILFT device is used to ensure the accuracy of the frequency translation. The PLL locks the LO to the incoming signal, and also synchronizes the LO with the incoming signal’s phase. By doing this, the LO generates a periodic output waveform at a higher frequency than the incoming signal. This higher frequency waveform is then filtered and buffered to the IF output of the device. The output waveform is therefore a replica of the input signal, but at a higher frequency.

The applications of the 275PGILFT are varied. In telecommunications, they are used in receivers and transmitters to increase the frequency of the signal and make it more suitable for data transmission across long distances. They can also be used to convert a signal from one frequency to another for transmission over microwave links. In broadcasting, the 271PGILFT is frequently employed to extend the frequency range of TV and radio signals, as well as to reduce interference and distortions from multipath signals.

The 275PGILFT is a very versatile and reliable frequency translator which provides excellent linearity, low noise, and wide bandwidth. Its robust construction and small form factor make it ideal for applications where space is limited. Furthermore, its low power consumption makes it ideal for portable and battery-powered applications.

In summary, the 275PGILFT is an advanced development of the classical PLL frequency translator. It works by frequency multiplying the baseband signal, enabling signals in one band to be translated to a higher frequency. Its application field is wide, and is suitable for use in telecommunications, broadcasting, and other applications. Its features include low power consumption, low noise and excellent linearity. Its small form factor and robust construction make it ideal for a variety of applications where space is limited.
