WebLinear Technology’s LTC5599 IQ modulator is a versatile RF building block, offering low power consumption, high performance, wide frequency range and unique optimization capabilities. It simplifies radio transmitter design without sacrificing performance or efficiency. Notes WebIn digital modulation, minimum-shift keying (MSK) is a type of continuous-phase frequency-shift keying that was developed in the late 1950s by Collins Radio employees Melvin L. Doelz and Earl T. Heald. Similar to OQPSK, MSK is encoded with bits alternating between quadrature components, with the Q component delayed by half the symbol period.. …
