BLF2012LM37R2400A 詳細描述
Product Overview
BLF2012LM37R2400A is a Pulse Electronics 2.45 GHz matched filter-balun combo intended for CSR Bluetooth, WLAN and 2.4 GHz ISM radio front ends. The component combines balanced conversion or RFIC matching with frequency-selective filtering, reducing external component count and limiting unwanted spectral content. Confirmed selection information includes operating band: 2.4 GHz to 2.5 GHz; port impedance: 50 Ω unbalanced / conjugate match to CSR BC04/05/06 series; insertion-loss data: 2.5 dB typical, 2.8 dB max at 25°C and 3.5 dB max over -25°C to +85°C; phase information: 180° ±10° at 25°C and ±15° over temperature; attenuation data: At least 35 dB at 880-960 MHz and defined rejection in cellular and 4.8-5.0 GHz bands.
Exact Yageo/Pulse specification: 2.4-2.5 GHz filter-balun combo, 50 Ω input, CSR conjugate match, 2012 package and the listed loss, phase, amplitude and attenuation limits. 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 Legacy exact ordering code.

Quality & Sourcing
Antrex Electronics can support sourcing of BLF2012LM37R2400A 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.
