700 Mhz To 2.7 Ghz Quadrature Demodulator - Analog Devices

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 and are best driven from a 1:1 balun for optimum performance. Excellent demodulation accuracy is achieved with amplitude and phase balances ~0.05 dB and ~0.2, respectively. The demodulated in-phase (I) and quadrature (Q) differential outputs are fully buffered and provide a voltage conversion gain of ~4 dB. The buffered baseband outputs are capable of driving a 2 V p-p differential signal into 200 . By Analog Devices, Inc.
