Application

The AD8345 Modulator can be used as the IF transmit modulator 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 communication 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 package wite   exposed  paddle. Itsperformance  is specified over a 40°C to +85°C temperature range. This device is fabricated on  Analog Devices' advanced silicon bipolar process.

Description

The AD8345 is a silicon RFIC quadrature modulator, designed for use from 250 MHz
to 1000 MHz. AD8346's excellent phase accuracy 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 Ω drive at VOUT.
