DEA102500LT-9052A1

Product Overview

DEA102500LT-9052A1 is a TDK component developed for Bluetooth, WLAN and compact 2.4 GHz antenna-to-RFIC interfaces. This is a filtering component rather than a conventional transformer. Its role is to pass the intended RF band while reducing harmonic and out-of-band energy before the antenna, amplifier or receiver stage. Confirmed selection information includes operating band: 2.3 GHz to 2.5 GHz; port impedance: 50 Ω single-ended input; balanced output defined by the integrated network; insertion-loss data: 0.9 dB maximum; return-loss data: 15 dB minimum; phase information: 178° nominal phase difference.

Exact model: 2.3-2.5 GHz, 50 Ω input, 0.9 dB maximum insertion loss, 15 dB minimum return loss, 178° phase and 0402 package. RF layout should follow the manufacturer land pattern, with controlled impedance, short interconnects and appropriate grounding around the signal-conditioning network. The recorded lifecycle state is Active exact ordering record.

Quality & Sourcing

Antrex Electronics can support sourcing of DEA102500LT-9052A1 for production, repair and shortage requirements. Incoming verification can compare the exact manufacturer marking, ordering suffix, package, frequency range, port configuration and documented RF function. For legacy or obsolete components, date-code and condition review, visual inspection and third-party testing can be coordinated before shipment. Alternative parts should remain subject to engineering approval because a nearby family code may use a different impedance, winding arrangement, filter response, RFIC match or PCB footprint.
