The BAL-0020SLG from Marki Microwave is an SMT Balun / RF Transformer that operates from 10 MHz to 20 GHz. The balun transforms a 50 ? input to 100 ? differential output and is tuned for optimal phase/amplitude balance. It has an insertion loss of less than 4.5 dB and provides isolation of over 12 dB. The Balun is ideal for analog to digital converters, balanced receivers, baseband digital modulation, and signal integrity applications.
