GENERAL DESCRIPTION
The ADL5375 is a broadband quadrature modulator designed for
operation from 400 MHz to 6 GHz. Its excellent phase accuracy
and amplitude balance enable high performance intermediate
frequency or direct radio frequency modulation for commu-
nication systems.
The ADL5375 features a broad baseband bandwidth, along
with an output gain flatness that varies no more than 1 dB
from 450 MHz to 3.8 GHz. These features, coupled with a broad-
band output return loss of ≤−14 dB, make the ADL5375 ideally
suited for broadband zero IF or low IF-to-RF applications,

broadband digital predistortion transmitters, and multiband
radio designs.
The ADL5375 accepts two differential baseband inputs and
a single-ended LO. It generates a single-ended 50 Ω output.
The two versions offer input baseband bias levels of 500 mV
(ADL5375-05) and 1500 mV (ADL5375-15).
The ADL5375 is fabricated using an advanced silicon-germanium
bipolar process. It is available in a 24-lead, exposed paddle, Pb-free,
LFCSP_VQ package. Performance is specified over a −40°C to
+85°C temperature range. A Pb-free evaluation board is also
available.

THEORY OF OPERATION CIRCUIT DESCRIPTION The ADL5375 can be divided into five circuit blocks: the LO interface, the baseband voltage-to-current (V-to-I) converter, the mixers, the differential-to-single-ended (D-to-S) stage, and the bias circuit.

... Asserting DSOP further reduces LO leakage (see Figure 27 and Figure 52) and drives the broadband noise of the device down to just above the KT (thermal) noise level. Asserting DSOP also reduces the supply current of the ADL5375 from 200 mA to 131 mA. The time delay between when the DSOP pin is forced to ground and the output power is restored is approximately 200 ns ...

... Level-shifting can be achieved with either a passive network or an active circuit. A passive network of resistors is shown in Figure 62. In this network, the dc bias of the DAC remains at 500 mV while the input to the ADL5375-15 is 1500 mV. It should be noted that this passive level-shifting network introduces approximately loss in the ac signal. ...
