Analog Devices Inc. ADMV4420 K Band Downconverter
Analog Devices Inc. ADMV4420 K Band Downconverter is a highly integrated, double-balanced, active mixer with an integrated fractional-N synthesizer. The Analog Devices downconverter is ideal 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.
