MABA-009573-CF1A40

Product Overview

The MABA-009573-CF1A40 is a MACOM flux-coupled balun developed for 5 MHz to 100 MHz applications. Flux-coupled construction supports broad low-frequency response and magnetic coupling for IF, HF, VHF and lower-UHF signal paths. The moderate impedance step is suitable for connecting a conventional RF source to a higher-impedance balanced or transformed load.

Official MACOM catalogue: 1:1.77 flux-coupled balun, 5-100 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-009573-CF1A40 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.
