Baseband Design Example for LTC5589/LTC5599 Low-Power IQ Modulator

Bruce Hemp - Applications Section Leader Jul 1st 2016
Introduction This basic low power modulator was described in the LT Journal Nov 2015 article. In this blog post, we will show how to: Use simulation to validate the filter design, and Reduce DC offsets by utilizing Differential Amplifiers for the baseband drive. Also shown are some miscellaneous tips to help complete ...

A Very Low Power, High Performance I/Q Modulator

James Wong - Product Marketing Manager Nov 19th 2014
Modern digital transmitters take advantage of using high-order modulation to maximize data throughput rate while minimizing spectral bandwidth, thus allowing more efficient use of the frequency spectrum. I/Q modulators allow baseband signals to directly modulate onto the RF carrier. Such modulators typically suffer from excessive ...

DC2091A - LTC5599 | 30MHz to 1300MHz Low Power Direct I/Q Modulator - DC590B Serial Board Required

Sep 5th 2014
Demonstration circuit 2091A is optimized for evaluation of the LTC®5599 low power direct quadrature modulator. The balanced I and Q baseband input ports can be either AC- or DC-coupled to a source with a common mode voltage level of about 1.4V. Fixed LC networks on the LO and RF ports cover a continuous 90MHz to 1300MHz ...
