ANALOG DEVICES ADMV4530ACCZ

ADMV4530 is a highly integrated upconverter with an inphase/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 (LO) 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 100µs. The single-ended reference input to the PLL operates upto 500MHz and features internal reference dividers and a multiplier for added flexibility. Additionally, the phase frequency detector (PFD) comparison frequency can be upto 250 MHz for integer mode and 160MHz for fraction-N mode. It is used in application such as satellite communication, point to point microwave communication etc.
