ADMV4530 Upconverter with Integrated PLL+VCO (27-31GHz)

Analog Devices Inc. ADMV4530 Upconverter with Integrated PLL+VCO (27GHz to 31GHz) features 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  2x multiplier generate the necessary on-chip Local Oscillator  (LO) signal for the I/Q mixer. These aspects eliminate 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.
