GENERAL DESCRIPTION
The ADL5382 is a broadband quadrature I-Q demodulator that
covers an RF input frequency range from 700 MHz to 2.7 GHz.
With a NF = 14 dB, IP1dB = 14.7 dBm, and IIP3 = 33.5 dBm at
900 MHz, the ADL5382 demodulator offers outstanding dynamic
range suitable for the demanding infrastructure direct-conversion
requirements. The differential RF inputs provide a well-behaved
broadband input impedance of 50 Ω and are best driven from a
1:1 balun for optimum performance.
Excellent demodulation accuracy is achieved with amplitude and
phase balances ~0.05 dB and ~0.2°, 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.

Figure 1.
The fully balanced design minimizes effects from second-order
distortion. The leakage from the LO port to the RF port is
<−65 dBc. Differential dc offsets at the I and Q outputs are typically
<10 mV. Both of these factors contribute to the excellent IIP2
specifications which is >60 dBm.
The ADL5382 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 ADL5382 is fabricated using the Analog Devices, Inc.,
advanced Silicon-Germanium bipolar process and is available
in a 24-lead exposed paddle LFCSP.
