PRODUCT DESCRIPTION
The AD8346 is a silicon RFIC I/Q modulator for use from
0.8 GHz to 2.5 GHz. Its excellent phase accuracy and ampli-
tude balance allow high performance direct modulation to RF.
The differential LO input is applied to a polyphase network
phase splitter that provides accurate phase quadrature from
0.8 GHz to 2.5 GHz. Buffer amplifiers are inserted between
two sections of the phase splitter to improve the signal-to-noise
ratio. The I and Q outputs of the phase splitter drive the LO
inputs of two Gilbert-cell mixers. Two differential V-to-I con-
verters connected to the baseband inputs provide the baseband
modulation signals for the mixers. The outputs of the two mixers
are summed together at an amplifier which is designed to drive a
50
load.
This quadrature modulator can be used as the transmit modula-
tor in digital systems such as PCS, DCS, GSM, CDMA, and
ISM transceivers. The baseband quadrature inputs are directly
modulated by the LO signal to produce various QPSK and
QAM formats at the RF output.
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 AD8346 is supplied in a 16-lead TSSOP package, measur-
