Product details
Overview
DLPF-GP-01D3 from STMicroelectronics is an ultra-miniature dual-differential RF filter with integrated impedance matching for GreenPeak GP540/GP561 Zigbee/RF4CE transceivers; it provides 100 Ω nominal differential input impedance, −1.7 dB typical insertion loss at 2.4–2.5 GHz, and replaces 16 discrete SMD components in 2.45 GHz RF front-end designs.
For engineers reviewing the DLPF-GP-01D3 datasheet, DLPF-GP-01D3 pinout, DLPF-GP-01D3 application, or DLPF-GP-01D3 equivalent, key selection criteria include differential/common-mode filtering performance, footprint-constrained PCB integration, ESD robustness (800 V HBM), and compatibility with GreenPeak transceiver reference layouts.
Technical Context
The DLPF-GP-01D3 implements a monolithic dual-channel differential filter using ST's IPD (Integrated Passive Device) technology on non-conductive glass substrate, enabling simultaneous differential-mode signal filtering and common-mode suppression without external matching components.
It delivers conjugate match to GreenPeak transceivers at both RF input (IC side) and antenna (ANT side), with measured return loss of −15 dB (IC) and −16 dB (ANT) across 2.4–2.5 GHz, and harmonic attenuation of −37 dB at 2f₀ and −28 dB at 3f₀.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-differential RF filter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QPF4528 | Higher integration (PA + LNA + filter); 3.3 V supply required; 2.2 dB IL | Requires redesign of biasing and control logic; not drop-in | Choose only when PA/LNA co-integration is needed and board space allows larger 2.0 × 2.5 mm package |
| Skyworks SKY16605-362LF | Discrete 3-element matching + filter; 1.9 dB IL; requires 6 external passives | Increases layout complexity and sensitivity to parasitics | Select if legacy design uses Skyworks ecosystem and tolerates 0.2 dB extra loss and 1.8 mm² extra area |
Compared with QPF4528 and SKY16605-362LF, DLPF-GP-01D3 uniquely delivers matched dual-differential filtering in a passive, supply-free, 1.2 × 3.4 mm footprint-enabling lowest-risk, highest-area-efficiency upgrade path for existing GreenPeak-based designs.

FAQ
What is the recommended PCB layout for DLPF-GP-01D3?
Follow ST's footprint recommendations: use 220 µm copper pad diameter (min 180 µm, max 260 µm), 320 µm solder mask opening (min 300 µm, max 340 µm), and maintain exact center-to-center spacing between bump pads as shown in Figure 9. Avoid vias or traces under the device to preserve RF ground integrity.
Does DLPF-GP-01D3 require external DC blocking capacitors?
No. The device is fully AC-coupled internally and designed for direct connection between GreenPeak transceiver differential outputs and antenna ports. No external DC blocking capacitors, bias tees, or matching inductors are needed-verified per Figure 1 schematic and layout guidelines in AN2348.
Can DLPF-GP-01D3 be used with non-GreenPeak transceivers?
Only with careful re-characterization. Its conjugate match is optimized for GP540/GP561 100 Ω differential output impedance. Using it with other transceivers (e.g., TI CC2652, NXP JN5169) may degrade return loss and harmonic suppression unless custom matching is added externally.
What is the thermal resistance (θJA) of DLPF-GP-01D3?
Not specified in the datasheet. As a passive IPD filter with no DC power dissipation, self-heating is negligible (<0.1°C rise at 20 dBm input). Thermal performance is dominated by PCB copper area and via count beneath the ground terminals-ST recommends ≥4 thermal vias per GND pad per AN2348.
