MABA-011031

Product Overview

Designed for 5 MHz to 1.2 GHz, MABA-011031 provides a verified 1:1 transformer relationship. Transmission-line construction is used to maintain broadband balance and predictable impedance transformation at frequencies where winding capacitance and leakage inductance become important. The unity-ratio relationship preserves nominal impedance while converting or coupling the signal through the transformer.

Official MACOM catalogue: 1:1 transmission-line balun, 5-1200 MHz. At the upper end of the stated range, short interconnects, the manufacturer land pattern and balanced PCB routing are important to installed performance.

Quality & Sourcing

Antrex Electronics can support sourcing of MABA-011031 for production, repair and shortage requirements. Incoming verification can compare the exact MACOM ordering code, transformer ratio, operating band, topology, winding arrangement, package and tape-and-reel status. Because many MACOM transformer families contain closely related suffixes, an alternative should not be approved from frequency overlap alone; impedance ratio, tertiary or center-tap functions, pin orientation and PCB footprint must also match. Antrex Electronics can coordinate BOM sourcing and third-party inspection when legacy, obsolete or shortage material requires additional checks.
