SECOND ORDER CURRENT FEEDBACK OPERATIONAL AMPLIFIER (CFOA) ACTIVE-R BANDPASS FILTER FOR AERONAUTICAL MOBILE APPLICATIONS
Keywords:second order, CFOA, Bandpass, filter, Aeronautical mobile, Communications, Active-R.
Aeronautical mobile communication systems utilize Digital broadband data link technology between space and ground to achieve the interconnection and networking between planes and the ground during flight (Guo, 2013). This technology utilized i.e. Digital broadband data link between the space and ground at the link layer needed to solve the problem of multiple planes, a variety of crafts sharing limited radio resources between space and ground. Therefore the need for a filter comes into play to solve the problem of interference, in this respect, using the mechanism of bandwidth dynamic allocation and demand to solve the contradiction between resource utilization and service quality is an important research aspect, hence the second order CFOA Active-R Bandpass filter was designed, simulated and results presented. Results showed good agreement with filter specification, therefore it can be used in the implementation of the Aeronautical Mobile Communications system.
