EBAL-0050
10 MHz to 50 GHz Broadband Balun
The EBAL-0050 is an ultra-broadband 2:1 balun (unbalanced to balanced transformer), hand-tuned for optimal amplitude and phase balance. The EBAL-0050 transforms between a 50Ω common input and a 100Ω differential output. It operates over a 10 MHz to 50 GHz bandwidth, with typical 0.25 dB amplitude and 2° phase balance, low 4 dB insertion loss as a mode converter. The EBAL-0050 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-0050 is in a 1.5 x 1.5 inch connectorized package and features 2.40 mm Female connectors on the common input and differential output ports.

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.
Three port scattering parameters measured as three single-ended 50Ω ports showing relationship between any two ports.
The electrical specifications apply at TA=+25°C in a 50Ω system. Min and Max limits are guaranteed at TA=+25°C.
