Synth Ref. divider Functional Block Diagram Product Description The RFMD2080 is a low power, highly integrated, IQ modulator with integrated fractional-N synthesizer and voltage controlled oscillator (VCO). The RFMD2080 can generate output frequencies of between 45MHz and 2700MHz, making it suitable for a wide range of applications. The fractional-N synthesizer takes advantage of an advanced sigma-delta architecture that delivers ultra-fine step sizes and low spurious products. The synthesizer/VCO combined with an external loop filter allows the user to generate an oscillator signal covering 90MHz to 5400MHz. The signa...
