M/A-COM Technology Solutions has introduced a 2:1 flux coupled transformer for CATV applications. The MABA-011017 is a flux coupled transformer ideal for DOCSIS 3.0 applications. Packaged in a surface mount SM-138 package it exhibits low insertion loss and high return loss.

“The MABA-011017 has been specifically designed and optimized to work with next generation DOCSIS3.0 programmable gain amplifiers that require a 2:1 impedance match,” said Graham Board, Product Manager. “This part extends our offering of high performance DOCSIS Baluns which are highlighted in all leading PGA reference designs."

The MABA-011017 covers 5 to 85 MHz with a return loss of 19.0 dB and an insertion loss of 0.50 dB. The impedance ratio is 2:1.
