The gain control inputs are dc-coupled with a +/−500 mV dif-  
ferential full-scale range centered about a 500 mV common  
mode. The maximum modulation bandwidth is 230 MHz,  
which can be reduced by adding external capacitors to limit the  
noise bandwidth on the control lines.  
GENERAL DESCRIPTION  
The ADL5390 vector multiplier consists of a matched pair of  
broadband variable gain amplifiers whose outputs are summed.  
The separate gain controls for each amplifier are linear-in-  
magnitude. If the two input RF signals are in quadrature, the  
vector multiplier can be configured as a vector modulator or as  
a variable attenuator/phase shifter by using the gain control pins  
as Cartesian variables. In this case, the output amplitude can be  
controlled from a maximum of +5 dB to less than –30 dB, and  
the phase can be shifted continuously over the entire 360°  
range. Since the signal paths are linear, the original modulation  
on the inputs is preserved. If the two signals are independent,  
then the vector multiplier can function as a 2:1 multiplexer or  
can provide fading from one channel to another.  
Both the RF inputs and outputs can be used differentially or  
single-ended and must be ac-coupled. The impedance of each  
VGA RF input is 250 Ω to ground, and the differential output  
impedance is nominally 50 Ω over the operating frequency  
range. The DSOP pin allows the output stage to be disabled  
quickly to protect subsequent stages from overdrive. The  
ADL5390 operates off supply voltages from 4.75 V to 5.25 V  
while consuming 135 mA.  
The ADL5390 is fabricated on Analog Devices’ proprietary,  
high performance 25 GHz SOI complementary bipolar IC  
process. It is available in a 24-lead, Pb-free CSP package and  
operates over a −40°C to +85°C temperature range. Evaluation  
boards are available.  
The ADL5390 operates over a wide frequency range of 20 MHz  
to 2400 MHz. For a maximum gain setting on one channel at  
380 MHz, the ADL5390 delivers an OP1dB of 11 dBm, an OIP3  
of 24 dBm, and an output noise floor of −148 dBm/Hz. The gain  
and phase matching between the two VGAs is better than 0.5 dB  
and 1°, respectively, over most of the operating range.
