Baluns are three port devices used to convert unbalanced signaling to balanced signaling, or vice-versa. Standard single port scattering parameters (s-parameters) fail to convey the common mode or differential mode response of the balanced, or differential port. This application note explains how mixed-mode s-parameters can be deployed to provide this useful information.

AN-009: Comparison of 110 GHz Silicon (HL9439) and Ceramic (HL8439) DC Blocks
Application Note # AN-009 presents the tradeoffs between using 110 GHz DC Blocks made with Silicon (HL9439) and Ceramic (HL8439) substrates.

AN-008: Linear Amplifiers and Transition Time Converters for 10Gbaud PAM4 Applications
Measurements presented in Application Note # AN-008 to show that HYPERLABS’ broadband linear amplifiers perform exceptionally well in PAM4 applications at 10Gbaud.

AN-006: Common Mode Rejection of the HYPERLABS’ HL940X Series Baluns
Application Note # AN-006 focuses on differential to single-ended conversion versus single-ended measurements. We will show that using a balun with a high Common Mode Rejection Ratio (CMRR) will be beneficial to the designer only if common mode signals are present on the differential signal.
