Single 5 V supply APPLICATIONS Cellular W-CDMA/CDMA/CDMA2000/GSM Microwave point-to-(multi)point radios Broadband wireless and WiMAX GENERAL DESCRIPTION The ADL5382 is a broadband quadrature I-Q demodulator that The fully balanced design minimizes effects from second-order covers an RF input frequency range from 700 MHz to 2.7 GHz. distortion. The leakage from the LO port to the RF port is With a NF = 14 dB, IP1dB = 14.7 dBm, and IIP3 = 33.5 dBm at <65 dBc. Differential dc offsets at the I and Q outputs are typically 900 MHz, the ADL5382 demodulator offers outstanding dynamic <10 mV. Both of these factors contribute to the excellent IIP2 range suitable for the demanding infrastructure direct-conversion specifications which is >60 dBm. requirements. The differential RF inputs provide a well-behaved The ADL5382 operates off a single 4.75 V to 5.25 V supply. The broadband input impedance of 50 and are best driven from a supply current is adjustable with an external resistor from the 1:1 balun for optimum performance. BIAS pin to ground. Excellent demodulation accuracy is achieved with amplitude and The ADL5382 is fabricated using the Analog Devices, Inc., phase balances ~0.05 dB and ~0.2, respectively. The demodulated advanced Silicon-Germanium bipolar process and is available in-phase (I) and quadrature (Q) differential outputs are fully in a 24-lead exposed paddle LFCSP. 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 . Rev. A Information furnished by Analog Devices is believed to be accurate and reliable.
