  Abstract

In this paper, we describe the transmitter of the VHF Data Exchange System (VDES), which is part of the e-Navigation Strategy Implementation Plan, which is currently being discussed around the International Association of Lighthouse Authorities(IALA). In the VDES recommendation, the spectral mask specification of transmitter has a strict specification to minimize interference between adjacent channels. In this paper, we describe the linearization technic of transmitter to meet this requirement and design and fabricated a transmitter using Cartesian Feedback Loop technic. Through the fabricated transmitter, we measured the spectrum mask of the transmitter output of each Modulation Coding Scheme (MCS) of the Application Specific Message (ASM) channel and the VHF Data Exchange (VDE) channel in the VDES frequency band. As a result of the measurement, it satisfies the standard recommended by the IALA and confirmed that it suppressed the Inter-Modulation Distortion (IMD) component by about 30dBc compared to the case of not using the linearization technique.
