This application note presents a guide in crystal selection for proper FSK modulation with Melexis transmitter integrated circuits. It presents the different types of crystal together with its ...

The TH72031 is an FSK transmitter integrated circuit operating at a frequency range of 850 MHz to 930 MHz. It features an FSK through crystal pulling allows modulation from DC to 40 kbps and offers a ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Direct modulation of a laser 1 has always been used in optical telecommunications. Although distance–capacity product capabilities using this approach have been limited, it represents a very ...
