Detailed Description for HHM15112A1
Product Overview
HHM15112A1 integrates the balanced/unbalanced transformation required in 900 MHz to 2.2 GHz signal paths. The 1:1.33 relationship connects the 75 Ω unbalanced / 100 Ω balanced ports while preserving the balance, loss and package characteristics published for this exact TDK ordering code. Confirmed selection limits include insertion loss of 1.1 dB maximum, return loss of 10 dB minimum, amplitude balance of 0 dB ±2 dB, phase balance of 180° ±15°.
The 75 Ω-to-100 Ω transformation is intended for broadband coaxial tuner paths feeding differential receiver ICs. The winding ratio, port impedance, package dimensions and lifecycle status should all be checked during replacement review; related ATB or HHM products may have different balanced impedances or center-tap arrangements.
