GENERAL DESCRIPTION
The ADL5387 is a broadband quadrature I/Q demodulator that
covers an RF/IF input frequency range from 50 MHz to 2 GHz.
With a NF = 13.2 dB, IP1dB = 12.7 dBm, and IIP3 = 32 dBm @
450 MHz, 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 Ω 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 ~0.05 dB and
~0.4°, 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 Ω.

The fully balanced design minimizes effects from second-order
distortion. 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 IIP2
specifications > 60 dBm.
The ADL5387 operates off a single 4.75 V to 5.25 V supply. The
supply current is adjustable with an external resistor from the
BIAS pin to ground.
The ADL5387 is fabricated using the Analog Devices, Inc.
advanced silicon-germanium bipolar process and is available in
a 24-lead exposed paddle LFCSP.
