GENERAL DESCRIPTION
independent of differential load impedances as low as 100 Ω
with a drive capability exceeding 2Vpp in to 200 Ω.
The ADL5380 is a high performance quadrature I-Q
demodulator that covers an RF input frequency range from 400
MHz to 6 GHz. With a NF = 13dB, IP1dB = 12dBm and IIP3 =
31dBm at 2.5GHz, the demodulator offers good dynamic range
suitable for the demanding infrastructure direct-conversion
requirements. The differential RF inputs provide a well-behaved
broad-band input impedance of 50Ω and should be driven from
a 1:1 balun for best performance.
The fully balanced design minimizes effects from 2nd order
distortion. The leakage from the LO port to the RF port is
60dBc. Differential DC-offsets at the I and Q outputs are
<10mV. Both of these factors contribute to the excellent IIP2 of
>60dBm.
<-
The ADL5380 operates off a 4.75V to 5.25V supply with a
typical supply current of 200mA. The ADL5380 is fabricated
using Analog Devices’ advanced Silicon-Germanium bipolar
process and is available in a 24-lead exposed paddle LFCSP
package. Performance is specified over a -40oC to +85oC
temperature range.
Excellent quadrature accuracy is achieved using on-chip poly-
phase filters for LO quadrature generation. Over a wide range of
local oscillator (LO) levels, excellent demodulation accuracy is
achieved with phase and amplitude balances < 0.25 dB and <
0.5o, respectively. The demodulated in-phase (I) and quadrature
(Q) differential outputs are fully buffered. The ADL5380
provides a typical voltage conversion gain of 4dB

Preliminary Technical Data
EVALUATION BOARD
The ADL5382 evaluation board is available. There are two versions of the board, optimized for performance for separate frequency
ranges. For operation < 3GHz, an FR4 material based board with the ETC1-1-13 balun footprint is available. For operation between
3GHz to 4GHz, a Rogers material based board with the Johanson 3600BL14M050 balun footprint is available.
The board can be used for single-ended or differential baseband analysis. The default configuration of the board is for single-ended baseband
analysis.

provide a means to bypass the 9:1 TCM9-1 transformer to allow for differential baseband
