초록

In the design of vehicle glass antenna system, it is essential to use preamplifier between the glass antenna and the TV set, since glass antenna has low gain. In this paper, the preamplifier has been designed in the frequency range from 50MHz to 900MHz with the gam of 10dB. A negative feedback technique has been employed for the wideband characteristics of the amplifler. A DC block capacitor is also used to obtain flat gain response in the wide frequency range. The experimental result shows 1dB ripple in 9dB gain and 0.5dB ripple in 3dB noise figure. The test results were compared with those of the performed by the EEsof-touchstone.
