| Abstract: |
| There exist technical limitations in traditional Automa
tic Level Control (ALC) method, such as power overshoot
and longer establishment time.In this paper,an improved ALC circuit using Frequ
ency Hopping (FH) time clock to prohibit power transmission is proposed. The eng
ineering practice has proven that the improved ALC circuit can effectively overc
ome the above-mentioned limitations and it has been successfully applied in a FH
radio. |
