Abstract
In this paper, wish to improve reception performance of general receiver manufacturing maritime broadband reception amplifier that can thread easily in VHF transmit-receive equipment into downsize, light weight, low-coat. Manufactured reception amplifier expressed Characteristic that improve reception sensitive 3dBm in $140MHz\~170MHz$ frequency band. Therefore, may use communications equipment that utilize VHF wide-band more efficiently. Also, practical use degree is considered to be very high because telecommunication of good quality is available.
