Detailed Description for HHM1521
Product Overview
HHM1521 is a TDK multilayer or wound surface-mount RF balun transformer specified for 2.4 GHz to 2.5 GHz. The 1:4 relationship converts the 50 Ω unbalanced / 200 Ω balanced ports and establishes the differential load expected by the connected RF stage. Confirmed selection data includes insertion-loss performance of 1.0 dB maximum, return loss of 10 dB minimum, phase balance of 180° ±10°.
The device is intended for 2.4 GHz WLAN and Bluetooth RFICs requiring a 200 Ω balanced input. Its compact footprint lets the balun sit close to the RFIC, reducing the additional phase error and mismatch introduced by long differential PCB traces. The recorded lifecycle state is EOL announced, so the part is principally relevant to legacy production, repair and shortage sourcing.

Quality & Sourcing
Antrex Electronics can support sourcing of HHM1521 for production, repair and shortage requirements. Incoming verification can compare the exact manufacturer marking, ordering suffix, package dimensions, frequency range, single-ended and balanced impedances, insertion-loss limits and lifecycle status. For obsolete or NRND devices, Antrex Electronics can also coordinate BOM sourcing and third-party inspection before shipment, while alternative parts should remain subject to engineering approval for PCB footprint, impedance and RF performance.
