- Application Note AN5337 âApplication of the
CA3028 Integrated Circuit Ampliï¬er in the HF and
VHF Ranges.â This note covers characteristics of
different operating modes, noise performance,
mixer, limiter, and ampliï¬er design considerations
The CA3028A and CA3028B are differential/cascode
ampliï¬ers designed for use in communications and industrial
equipment operating at frequencies from DC to 120MHz.
The CA3028B is like the CA3028A but is capable of pre-
mium performance particularly in critical DC and differential
ampliï¬er applications requiring tight controls for input offset
voltage, input offset current, and input bias current.
The CA3053 is similar to the CA3028A and CA3028B but is
recommended for IF ampliï¬er applications.
