GP2Y+ Visão geral
A power splitter/combiner is a passive RF component that divides an input signal into two equal-amplitude outputs (splitter mode) or combines two inputs into a single output (combiner mode). It belongs to the broader category of RF power dividers within signal conditioning components, used in wireless infrastructure, test instrumentation, and phased-array systems. The 2-way topology (one input, two outputs) makes it the most common building block in distribution networks where signal coherence and amplitude balance matter.
The GP2Y+ uses Mini-Circuits' proprietary GaAs MMIC process with on-chip resistors for the resistive-divider network, which provides inherently broadband behavior across the 1600-3300 MHz band. The exposed-pad 12-VQFN package (DQ1225) yields a low thermal-resistance path and a compact 3x3 mm footprint suitable for high-density PCB designs. Internal dissipation handling and wideband phase tracking support multi-section use cases such as corporate-feed networks in antenna arrays.
Typical applications include LTE/4G and 5G sub-6 GHz infrastructure, in-building DAS (distributed antenna systems), Wi-Fi 2.4 GHz band signal sampling, RFID reader splitting networks, and RF test equipment where repeatable signal division with low loss is required. Its small size and zero-bias operation make it especially attractive for compact module designs.
When designing with the GP2Y+, follow the recommended PCB layout (PL-282) on Rogers RO4350B dielectric with continuous bottom-side ground. Maintain 50 ohm trace impedance from input to the splitter junction and from each output port; insufficient trace width degrades VSWR and worsens amplitude balance. Avoid routing DC or digital signals near the RF traces to prevent coupling.

Aplicações típicas
GP2Y+ é adequado para 6 aplicaçãos: LTE / 4G Base-Station Distribution, 5G Sub-6 GHz Small-Cell / Femtocell, In-Building Distributed Antenna Systems (DAS), Wi-Fi 2.4 GHz / ISM Band Signal Sampling, RFID Reader Split/Combine Networks, RF Test & Measurement Equipment.
LTE / 4G Base-Station Distribution
The GP2Y+ fits LTE/4G base-station distribution networks because its 1600-3300 MHz band directly overlaps LTE bands 1, 2, 3, 4, 7, 10, 25, 38, 40, and 41. With 17 dB minimum isolation between output ports, the GP2Y+ prevents cross-talk between sectors or MIMO streams that share a common feed. Placed at the corporate-feed junction of a 2x2 or 4x4 MIMO radio, the 1.5 dB insertion loss adds less than 0.4 dB per branch to the link budget. As a passive GaAs MMIC it draws zero DC and survives -40C to +85C outdoor enclosure conditions.
Recomendado
5G Sub-6 GHz Small-Cell / Femtocell
The GP2Y+ supports 5G sub-6 GHz small-cell and femtocell radios because the 1600-3300 MHz range covers 5G NR bands n7, n38, n40, and n41. With a 12-VQFN exposed-pad (3x3 mm DQ1225) footprint, the GP2Y+ allows dense placement next to RFICs in compact small-cell modules. The 4 degree max amplitude/phase imbalance preserves beam-pointing accuracy in phased-array corporate-feed networks, and the 1.2:1 typical VSWR keeps mismatch loss below 0.1 dB at each split.
Recomendado
In-Building Distributed Antenna Systems (DAS)
The GP2Y+ suits in-building DAS head-end and remotes because it splits downlink signals to multiple radiating antennas or combines uplink signals from multiple antennas with 17 dB minimum port-to-port isolation. This isolation prevents antenna-to-antenna coupling that would otherwise create multipath fading or self-interference in the same RF chain. Its -40C to +85C industrial temperature rating handles unconditioned telecom closets, and the RoHS-compliant surface-mount DQ1225 case supports automated high-volume assembly.
Recomendado
Wi-Fi 2.4 GHz / ISM Band Signal Sampling
The GP2Y+ operates across the 2.4 GHz Wi-Fi / ISM band (2400-2483.5 MHz), sitting well inside its 1600-3300 MHz passband. Used as a tap/sampler, the 2-way topology allows a -10 dB or -20 dB resistive-divider tap to feed a monitor or spectrum-analyser port while the main path continues to the antenna - with only 1.5 dB insertion loss on the through path. The passive nature keeps cost low in high-volume consumer access points, and the small DQ1225 footprint fits next to the Wi-Fi FEM.
Recomendado
RFID Reader Split/Combine Networks
The GP2Y+ covers the 2.4 GHz and select sub-3 GHz RFID bands, supporting reader architectures that drive multiple antennas from a single transmitter. Placing the GP2Y+ at the corporate-feed point of two reader antennas gives 17 dB minimum isolation, so leakage from one antenna does not de-sense the other receiver channel. With 4 degree max phase imbalance, the GP2Y+ enables accurate time-of-arrival-based localisation, and GaAs MMIC passive operation suits battery-powered handheld readers.
Recomendado
RF Test & Measurement Equipment
The GP2Y+ is a good fit for RF test and measurement signal-conditioning modules such as signal-generator fan-outs, ATE test-head combiners, and switch-matrix distribution networks. Its 1.5 dB typical insertion loss is calibrated-out easily in vector-corrected test systems, while the 1.2:1 typical VSWR keeps measurement uncertainty low. The 12-VQFN exposed-pad case is friendly to ATE handler trays and pick-and-place assembly, and zero DC bias keeps the BOM small.

Principais diferenciais
- Broadband 1600-3300 MHz with single part number (vs Narrow-band 2-way splitters in 2.4 GHz ISM band only)
- Passive MMIC, zero DC bias (vs Active splitter variants requiring bias-tee and DC regulator)
- Compact 12-VQFN exposed-pad DQ1225 (vs Larger SOT-89 or connectorized splitter footprints)
Notas de projeto
Follow Mini-Circuits suggested PCB layout PL-282 for the GP2Y+: Rogers RO4350B dielectric 0.020 inch +/- 0.0015 inch, 1/2 oz copper each side, continuous bottom ground plane. Signal traces are not allowed inside the hatched keep-out region around the exposed pad. Other stack-ups may require trace-width/gap recalculation to keep 50 ohm impedance.
Place the GP2Y+ input port closest to the upstream amplifier or mixer to minimize common-mode coupling and trace loss. Maintain 50 ohm trace geometry on all three RF ports (IN, OUT1, OUT2); bend angles should be mitered and via-count minimized. Multiple GND vias around the exposed pad are required for thermal and RF grounding.
Do not route DC, digital, or noisy power traces under or beside the GP2Y+ RF traces - coupling can degrade isolation below the 17 dB minimum and induce amplitude imbalance. Verify the + suffix in the part number before ordering to ensure RoHS-compliant material set. Storage and operating temperature are both -40C to +85C per datasheet.
Estimated: GP2Y+ maximum internal dissipation is approximately 0.5 W typical for a resistive-divider splitter at full input power; with the DQ1225 exposed pad and proper bottom-side thermal via array, junction-temperature rise is well within the 85C operating limit at typical RF input levels of +20 dBm per port.
