#617PT-2291=P3

Product Overview

For DOCSIS broadband amplifier output and frequency-mixer networks, #617PT-2291=P3 supplies the device-specific RF function defined by its ordering code. The Three-winding construction with turns 2T / 2T / 6T relationship defines how the single-ended, balanced or transformed ports interact and should remain unchanged when evaluating replacements. Confirmed selection information includes operating band: Specified at discrete points from 5 MHz to 200 MHz; port impedance: Winding-defined RF transformer interface; insertion-loss data: 1.0 dB max at 5 and 50 MHz; 1.5 dB max at 100 MHz; 2.0 dB max at 200 MHz.

Exact Murata winding table: 2T / 2T / 6T; Winding-defined RF transformer interface; 1.0 dB max at 5 and 50 MHz; 1.5 dB max at 100 MHz; 2.0 dB max at 200 MHz. 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 / discontinued family.

Quality & Sourcing

Antrex Electronics can support sourcing of #617PT-2291=P3 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.
