DLPF-GP-01D3

Product Overview

For GreenPeak Zigbee and RF4CE low-power wireless transceiver front ends, DLPF-GP-01D3 supplies the device-specific RF function defined by its ordering code. The integrated network combines differential low-pass filtering, common-mode filtering and chip-specific impedance matching, replacing a larger discrete RF network. The public ordering record confirms the manufacturer, device class, assembly format and lifecycle status; no unsupported electrical values are inserted.

ST identifies DLPF-GP-01D3 as an ultra-miniature dual differential filter with low-pass, common-mode and matching functions for GreenPeak transceivers. 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 The recorded lifecycle state is Obsolete / out of production.

Quality & Sourcing

Antrex Electronics can support sourcing of DLPF-GP-01D3 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.
