The LE79R70-1FQCT is a multifunctional transmitter for telecommunication applications. It has a wide range of applications, from low-speed communications to high-speed data transmission. It features enhanced features such as: low power consumption, wide temperature operating range, low input power and high output powers.

The LE79R70-1FQCT is typically used in telecommunication applications where a reliable, high performance data transmission is required. Its main application fields include mobile, wireless and broadband communication systems. It is also used in digital access switching systems, wireless LAN and metropolitan area networks.

The working principle of the LE79R70-1FQCT is based on the quadrature modulation technique. Quadrature modulation is a highly efficient modulation technique that allows the transmission of data and voice signals in a single frequency band. This technique enables the LE79R70-1FQCT to transmit both analogue and digital signals in a single frequency band.

The LE79R70-1FQCT has an integrated phase-locked loop (PLL) for clock recovery and an adjustable power amplifier for signal power adjustment depending on the transmission distance. The PLL ensures a stable and accurate signal and the amplifier provides the necessary average and peak output power levels. The amplifier is adjustable up to 50 mW, while the PLL ensures clock recovery up to 40 Mbits/sec. The LE79R70-1FQCT also features a programmable delay line for phase-shift compensation. This feature serves to minimize phase errors due to reflections from the air interface and to maintain a predetermined phase-shift in the transmission.

The LE79R70-1FQCT also features an integrated surge protector for protection against electromagnetic interference. An adjustable equalizing circuit also helps to improve signal quality by compensating for transmission line losses, as well as for non-linearities in the transmission path.

The LE79R70-1FQCT is an extremely flexible and high performance transmitter for telecommunication applications. It offers a wide operating voltage range, low power consumption, and advanced features such as adjustable power and phase-shift, integrated surge protector and high output power levels. The LE79R70-1FQCT provides an optimal solution for data transmission over long distances.
