The common radio transmission and reception activities are accomplished through modulation at single carrier frequency. Channels linking information sources and receivers are one of the fundamental blocks of all communication system. In free space, the signal for transmission and reception suffers from diffraction, scattering and interference due to the presence of dust particles, rain drops, heat and other obstacles. A concurrent dual band receiver is designed to operate at two frequency band with two Local Oscillators (LO) at the detection level. A frequency multiplier is introduced to use Single Oscillator (SO). This architecture reduces component cost, low power consumption and complexity of the receiver thereby enhancing its performance.
