MABA-011039

Product Overview

For RF signal paths from 1 MHz to 300 MHz, MABA-011039 supplies the stated 1:4 impedance transformation. Flux-coupled construction supports broad low-frequency response and magnetic coupling for IF, HF, VHF and lower-UHF signal paths. The ratio provides a meaningful voltage and impedance step for differential amplifiers, detectors, tuners and mixer interfaces.

Official MACOM catalogue: 1:4 flux-coupled balun, 1-300 MHz. The exact winding orientation and pin assignment should be retained because neighboring MACOM parts may share a frequency range while using a different ratio or topology.

Quality & Sourcing

Antrex Electronics can support sourcing of MABA-011039 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.
