ANALOG DEVICES ADMV4530BCCZ

ADMV4530 is a dual-mode, Ka band upconverter with integrated fractional-N PLL and VCO. This is a highly integrated upconverter with an in phase/quadrature (I/Q) mixer that is ideally suited for next generation Ka band satellite communications. An integrated low phase noise, fractional-N phase-locked loop (PLL) with a voltage controlled oscillator (VCO) and internal 2× multiplier generate the necessary on-chip local oscillator signal for the I/Q mixer, eliminating the need for external frequency synthesis. The VCO uses an internal autocalibration routine that allows the PLL to select the necessary settings and locks in approximately 10µs. The single-ended reference input to the PLL operates up to 500MHz and features internal reference dividers and a multiplier for added flexibility. Applications include satellite communication, point to point microwave communication.
