Detailed Description for HHM1902B1
Product Overview
HHM1902B1 is intended for 2400 MHz to 2500 MHz front ends where a small production balun is required. The unity-ratio network preserves the nominal 50 Ω unbalanced / 50 Ω balanced relationship while generating the balanced RF pair required by a differential device. Published selection limits include 0.8 dB maximum insertion loss, 10 dB minimum return loss, 0 dB ±2 dB amplitude balance and 180° ±10° phase balance.
2.4 GHz WLAN and Bluetooth front ends. TDK lists this exact ordering code as a production product, which is useful when maintaining an active wireless BOM. The compact multilayer package should be placed close to the RFIC, using the published land pattern and short, electrically symmetrical balanced traces.

Quality & Sourcing
Antrex Electronics can support sourcing of HHM1902B1 for production, repair and shortage requirements. Incoming verification can include manufacturer marking, dimensions, impedance and frequency review, date-code inspection and third-party testing when requested. For obsolete or NRND parts, the exact balanced impedance, package and suffix should remain unchanged until an engineering-approved alternative is validated.
