MABA-011015

Product Overview

For RF signal paths from 45 MHz to 1.2 GHz, MABA-011015 supplies the stated 1:2.78 impedance transformation. Transmission-line construction is used to maintain broadband balance and predictable impedance transformation at frequencies where winding capacitance and leakage inductance become important. The moderate impedance step is suitable for connecting a conventional RF source to a higher-impedance balanced or transformed load.

Official MACOM catalogue: 1:2.78 transmission-line balun, 45-1200 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-011015 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.
