PRODUCT DESCRIPTION
The AD8345 is a silicon RFIC quadrature modulator, designed
for use from 250 MHz to 1000 MHz. Its excellent phase accu-
racy and amplitude balance enable the high performance direct
modulation of an IF carrier.
The AD8345 accurately splits the external LO signal into two
quadrature components through the polyphase phase-splitter
network. The two I and Q LO components are mixed with the
baseband I and Q differential input signals. Finally, the outputs
of the two mixers are combined in the output stage to provide a
single-ended 50
drive at VOUT.
APPLICATIONS
The AD8345 Modulator can be used as the IF transmit modu-
lator in digital communication systems such as GSM and PCS
transceivers. It can also directly modulate an LO signal to
produce QPSK and various QAM formats for 900 MHz com-
munication systems as well as digital TV and CATV systems.
Additionally, this quadrature modulator can be used with direct
digital synthesizers in hybrid phase-locked loops to generate
signals over a wide frequency range with millihertz resolution.
The AD8345 Modulator is supplied in a 16-lead TSSOP pack-
age with exposed paddle. Its performance is specified over a
–40
°
C to +85
°
C temperature range. This device is fabricated on
Analog Devices’ advanced silicon bipolar process.
