The ADL5387 is a broadband quadrature I/Q demodulator thatcovers an RF/IF input frequency range from 30 MHz to 2 GHz.With a NF = 13.2 dB, IP1dB = 12.7 dBm, and IIP3 = 32 dBm at450 MHz, the ADL5387 demodulator offers outstanding dynamicrange suitable for the demanding infrastructure direct-conversionrequirements. The differential RF/IF inputs provide a well-behaved broadband input impedance of 50 Ω and are bestdriven from a 1:1 balun for optimum performance.Ultrabroadband operation is achieved with a divide-by-2 methodfor local oscillator (LO) quadrature generation. Over a widerange of LO levels, excellent demodulation accuracy isachieved with amplitude and phase balances ~0.05 dB and~0.4°, respectively. The demodulated in-phase (I) andquadrature (Q) differential outputs are fully buffered andprovide a voltage conversion gain of >4 dB. The bufferedbaseband outputs are capable of driving a 2 V p-p differentialsignal into 200 Ω.The fully balanced design minimizes effects from second-orderdistortion. The leakage from the LO port to the RF port is<−70 dBc. Differential dc-offsets at the I and Q outputs are<10 mV. Both of these factors contribute to the excellent IIP2specifications > 60 dBm.The ADL5387 operates off a single 4.75 V to 5.25 V supply. Thesupply current is adjustable with an external resistor from theBIAS pin to ground.The ADL5387 is fabricated using the Analog Devices, Inc.,advanced silicon-germanium bipolar process and is available ina 24-lead exposed paddle LFCSP.
