Broadband Marchand baluns were used to transform a single … It owns two attractive merits, i.e., its longer secure transmission distance and more convenient operation design. Thus, knowledge once in explicit form can be more easily distributed, but then it does need converting and assimilating into another person's tacit knowledge for application in a different context. Secure communication over long distances requires robust encryption. Basically, there are two types of transponders. During the first down-conversion to IF, any unwanted activity at a frequency spaced at f IF offset from the LO frequency (f LO) on the opposite side of f LO from the desired RF channel, will produce a mixing product falling right into the down-converted channel at f IF. Power Amplifier amplifies the power of frequency down converted signal (down link) to the required level. The main goal is to optimize the performance of the mixer in order to make it useful for applications in wireless communications around an RF frequency equal to 1.9 GHz.
