GENERAL DESCRIPTION
The ADL5382 is a broadband quadrature I-Q demodulator that covers an RF input frequency range from 700 MHz to 2.7 GHz. With a NF = 14 dB, IP1dB = 14.7 dBm, and IIP3 = 33.5 dBm at 900 MHz, the ADL5382 demodulator offers outstanding dynamic range suitable for the demanding infrastructure direct-conversion requirements. The differential RF inputs provide a well-behaved broadband input impedance of 50 Ω and are best driven from a 1:1 balun for optimum performance.
