The BAL-0012SSG from Marki Microwave is a 1:2 Balun (Balanced to Unbalanced Transformer) that operates from 10 MHz to 12 GHz. It transforms a 50-ohm input to 100-ohm differential (50-ohm single) output and has been tuned for optimal phase/amplitude balance. The balun has an insertion loss of less than 6.5 dB, isolation of 8 dB, and can handle 1 watt of input power. It has an amplitude balance of 0.6 dB, phase balance of 5-degrees, and a common-mode rejection of 26 dB. This RoHS-compliant, Pb-free balun is available in a surface-mount package and is ideal for analog to digital converters, balanced receivers, baseband digital modulation, and signal integrity applications.
