ADL5387ACPZ-WP

ADL5387 is a broadband quadrature I/Q demodulator that covers an RF/IF input frequency range from 30MHz to 2GHz. The ADL5387 demodulator offers outstanding dynamic range suitable for the demanding infrastructure direct-conversion requirements. The differential RF/IF inputs provide a well behaved broadband input impedance of 50 ohm and are best driven from a 1:1 balun for optimum performance. Ultrabroadband operation is achieved with a divide-by-2 method for local oscillator (LO) quadrature generation. Over a wide range of LO levels, excellent demodulation accuracy is achieved with amplitude and phase balances ~0.05dB and ~0.4°, respectively. Application includes QAM/QPSK RF/IF demodulators, W-CDMA/CDMA/CDMA2000/GSM, microwave point-to-(multi)point radios, broadband wireless and WiMAX, broadband CATVs.
