Detailed Description for CX2109NL
Product Overview
The CX2109NL is a Pulse Electronics ultra-wideband unity-ratio RF balun transformer developed for 4.5 MHz to 3 GHz signal paths. The unity-ratio network preserves the nominal impedance while converting between single-ended and balanced nodes. The confirmed frequency range, transformer ratio, topology and package are retained; unavailable numerical limits are omitted.
Its upper-frequency coverage reaches cellular, broadband wireless, MoCA or lower-microwave bands, so short and symmetrical PCB routing is important. This ordering code is supplied in tray packaging and is separate from the tape-and-reel T-suffix version. Transformer-coupled balanced conversion.

Quality & Sourcing
Antrex Electronics can support sourcing of CX2109NL for production, repair and shortage requirements. Incoming verification can compare the exact Pulse marking, electrical base model, packaging suffix, winding ratio, center-tap arrangement, frequency range and surface-mount dimensions. Antrex Electronics can also coordinate BOM sourcing and third-party inspection when legacy or shortage material requires additional authenticity and condition checks.
