ADMV4420ACPZ

ADMV4420ACPZ is a highly integrated, double-balanced, active mixer with an integrated fractional-N synthesizer, ideally suited for next-generation K band satellite communications. The RF front end consists of an integrated RF balun and low noise amplifier (LNA) for an optimal, 7dB, single-sideband noise figure while minimizing external components. Additionally, the high dynamic range IF output amplifier provides a nominal conversion gain of 36dB. An integrated low-phase noise, fractional-N, phase-locked loop (PLL) with a multicore voltage-controlled oscillator (VCO) and internal 2× multiplier generates the necessary on-chip LO signal for the double-balanced mixer, eliminating the need for external frequency synthesis. The multicore VCO uses an internal autocalibration routine that allows the PLL to select the necessary settings and lock in approximately 400µs. Applications include satellite communication, point to point microwave communication.
