EBAL-0026_10 MHz to 26 GHz Broadband Balun

Device Overview

General Description

The EBAL-0026 is an ultra-broadband 2:1 balun (unbalanced to balanced transformer), hand-tuned for optimal amplitude and phase balance. The EBAL-0026 transforms between a 50Ω common input and a 100Ω differential output. It operates over a 10 MHz to 26 GHz bandwidth, with typical 0.5 dB amplitude and 5° phase balance, low 3 dB insertion loss as a mode converter. The EBAL-0026 can be used for performing measurements on high frequency differential devices, including cables, microchips, and communication systems. It is an excellent choice for test & measurement benches, high speed analog-to-digital converters, balanced receivers, baseband digital modulations, and signal integrity. For accurate simulations, use the provided S3P file taken from measured production units. The EBAL-0026 is in a 1.5 x 1.5 inch connectorized package and features 2.92 mm Female connectors on the common input and differential output ports.

Typical Mixed Mode Performance Plots

Mixed mode scattering parameters are used to characterize differential circuits. For baluns, this means that the 0° and 180° ports become a single 100Ω differential port and the common port remains the same 50Ω common port. The two-port s-parameters of the balun are then characterized based on differential (d), common mode (c), or single-ended (s) signals. For example: Sds21 is the differential output response given a single ended input.
