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 ...

LTC6406: 133MHz Differential Amplifier with External Gain Set, Impedance Matching to a 75Ω Source and Level Shifting

Aug 3rd 2007
This circuit shows an example of a single-ended-to-differential amplifi er matching a 75Ω source and level shifting from a 2.5V input common mode to a 1.25V output common mode voltage (typical level shifting required from a 5V single-ended circuit to a 3V differential circuit to drive a high speed ADC). The singleended- ...
