The is a broadband Quadrature I/Q Demodulator that covers an RF/IF input frequency range from 30MHz to 2GHz. With a NF = 13.2dB, IP1dB = 12.7dBm and IIP3 = 32dBm at 450MHz, 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 50R and are best driven from a 1:1 balun for optimum performance. Ultra broadband 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. The demodulated in-phase I and quadrature Q differential outputs are fully buffered and provide a voltage conversion gain of >4dB. The buffered baseband outputs are capable of driving a 2Vp-p differential signal into 200R.
