GP2YA+ 概要
What is a power splitter/combiner: A power splitter is a passive RF component that divides an input signal into two (or more) equal-amplitude, equal-phase outputs, or conversely combines multiple inputs into a single output. The Wilkinson-style architecture provides matched 50Ω ports and high isolation between output paths, minimizing interaction between downstream stages. In the RF component hierarchy it sits below directional couplers and above simple resistive pads, and it is a foundational building block in any multi-antenna, multi-channel, or test-and-measurement RF signal chain.
Key differentiating features include a wide 1600-3300 MHz bandwidth covering the 2.4 GHz ISM band, Wi-Fi channels 1-13, and 2.6 GHz LTE bands, plus GaAs MMIC construction for repeatable performance versus traditional discrete Wilkinson designs. Excellent amplitude unbalance of 0.03 dB and 0.6 degree phase unbalance preserve signal integrity across both output paths.
Architecturally, the GP2YA+ integrates the Wilkinson splitter, internal 50Ω termination resistors, and matching networks into a single GaAs die. The exposed-pad VQFN-12 package provides a low-thermal-resistance path to the host PCB ground plane, which is essential for reliable operation at the 10 W splitter power rating.
Typical applications include 2.4 GHz Wi-Fi access points, small-cell and distributed-antenna-system (DAS) signal distribution, LTE/5G front-end modules operating in the 2.6 GHz band, and laboratory test instrumentation where repeatable amplitude and phase balance is critical.
A key design consideration is PCB layout: keep the ground paddle soldered to a continuous ground plane with abundant vias directly beneath the exposed pad. Maintain 50Ω controlled-impedance traces (typically CPW or microstrip) on all three RF ports to preserve the datasheet's 33 dB return-loss figure.
This page synthesizes cross-distributor pricing, drop-in alternatives, and PCB-level design notes that supplement the Mini-Circuits datasheet with information gain for sourcing and layout engineers.

主な用途
GP2YA+ の用途: 6 件s: 2.4 GHz Wi-Fi Access Point Front-End, LTE / 5G Small-Cell Signal Distribution, Test & Measurement - Multi-Channel RF Distribution, Distributed Antenna System (DAS) Signal Combining, ISM Band 2.4 GHz IoT Gateway, Microwave Backhaul Point-to-Point Radio.
2.4 GHz Wi-Fi Access Point Front-End
The GP2YA+ serves as the 2-way splitting element between the Wi-Fi baseband/MAC and the dual antenna chains in a 2.4 GHz access point or router, with its 1600-3300 MHz passband covering all 14 Wi-Fi channels (1-13 plus 14). The 22 dB typical isolation prevents one antenna chain's reflected power from leaking into the other, preserving MIMO throughput, while the 0.03 dB amplitude unbalance keeps the two spatial-stream paths at equal gain so the PHY layer does not have to compensate. Placed between the 2.4 GHz radio transceiver and the two antenna ports with 50Ω CPW traces and a via-fenced ground paddle, the GP2YA+ adds only 1.1 dB of insertion loss per path - a fraction of a dB that designers can recover via the AP's built-in Tx power calibration.

LTE / 5G Small-Cell Signal Distribution
In a 2.6 GHz LTE small-cell or distributed-antenna system the GP2YA+ splits the base-station output to two remote radio heads or two antenna panels with its matching 1600-3300 MHz response covering Band 7, Band 38, and Band 41 (TDD). The 10 W power-handling capability supports typical small-cell transmit power levels from a few hundred milliwatts up to multi-watt operation without external attenuation, while 33 dB return loss preserves the closed-loop digital-pre-distortion accuracy required by 4G/5G base stations. Used as a 1-to-2 splitter the GP2YA+ keeps phase coherent across both paths (0.6 deg typical phase unbalance), which is essential for the MIMO and beamforming accuracy demanded by 5G NR deployments.
おすすめ
Test & Measurement - Multi-Channel RF Distribution
Bench-top signal generators, spectrum analyzers, and vector network analyzers use the GP2YA+ to route a single test stimulus to two device-under-test channels while keeping both paths amplitude-matched and phase-matched. The 0.03 dB amplitude unbalance and 0.6 degree phase unbalance minimize the calibration overhead between the two paths, and the 22 dB isolation prevents a DUT on port 2 from injecting back into port 1 during S-parameter sweeps. Housed in the 12-VQFN exposed-pad package it integrates cleanly onto evaluation boards alongside Mini-Circuits' other MMIC splitters, couplers, and attenuators for a complete lab-bench RF front-end.
おすすめ
Distributed Antenna System (DAS) Signal Combining
Used in reverse - as a 2-way combiner - the GP2YA+ merges two antenna feeds into a single feed for a base-station receiver in a 2.6 GHz LTE DAS deployment. The 22 dB isolation between the two combining ports prevents noise picked up by one antenna from coupling into the other receiver chain, while the 10 W power rating supports in-building DAS where the combined uplink signal stays well below the splitter rating. The 0.6 degree phase unbalance ensures the two antenna paths add coherently rather than canceling, which directly improves the uplink SNR of the DAS hub.
おすすめ
ISM Band 2.4 GHz IoT Gateway
Industrial IoT gateways operating in the 2.4 GHz ISM band leverage the GP2YA+ to drive two antenna diversity branches from a single radio, improving link reliability in factory or warehouse environments where multipath fading is severe. The 1600-3300 MHz passband covers Bluetooth, Zigbee, Thread, and Matter radio protocols all sharing the 2.4 GHz ISM band, so a single GP2YA+ supports multi-protocol gateway designs. Antenna diversity gain from the second branch (typically 3-5 dB at the link level) more than offsets the 1.1 dB insertion loss of the splitter for stationary installations.
おすすめ
Microwave Backhaul Point-to-Point Radio
In 2.5-2.7 GHz point-to-point microwave backhaul links the GP2YA+ splits the IF or LO signal to the mixer pair on the receive side, where 0.03 dB amplitude unbalance and 0.6 degree phase unbalance preserve the I/Q quadrature match that sets the image-rejection ratio of the demodulator. The 22 dB typical isolation prevents local-oscillator leakage between the two mixer ports, which would otherwise degrade the receiver noise figure. Used in conjunction with a 50Ω printed balun on the PCB, the GP2YA+ enables compact 2.5-2.7 GHz backhaul designs without sacrificing receiver performance.

設計ノート
The VQFN-12 exposed thermal pad is the primary RF ground reference for the GP2YA+. Solder it directly to a continuous, uninterrupted ground plane and place a dense via fence (≥9 vias, 0.3 mm diameter, 0.5-1.0 mm pitch) directly under the pad for low-inductance grounding. Skipping the via fence degrades both isolation and return loss by 3-5 dB compared to the datasheet's 22 dB / 33 dB figures.
Maintain 50Ω controlled-impedance traces on all three RF ports (typically CPW-on-ground or microstrip on standard FR-4 with 0.8-1.0 mm dielectric). Keep RF traces straight, avoid 90-degree bends (use mitered or curved corners), and isolate the input/output ports by at least 1.5× the substrate height to preserve the datasheet's 22 dB typical isolation figure.
At the 10 W maximum input power rating the GP2YA+ dissipates the difference between input and twice the per-port output power; in a Wilkinson splitter the internal termination resistor can see up to roughly 0.5-1 W of dissipation. The exposed-pad VQFN-12 thermal resistance of approximately 35-40 C/W (estimated, datasheet does not specify) means the die can rise 20-40 C above PCB temperature at full rated power - ensure adequate copper area on the host PCB for continuous-wave operation.
Estimated from the datasheet: amplitude unbalance of 0.03 dB and phase unbalance of 0.6 deg translate to roughly 0.7% amplitude error and 0.01 rad phase error - well below the 1 dB / 5 deg budget for typical Wi-Fi AP, LTE small-cell, and DAS receive chains. For beamforming applications the phase unbalance directly biases the beam-steering angle, so verify it remains within the array calibration tolerance across temperature.
Do not apply DC to any RF port - the GP2YA+ has internal DC blocks on all three RF ports, but exceeding the datasheet's ESD rating on those ports can permanently damage the GaAs MMIC die. Also avoid routing digital or noisy power traces across the GP2YA+ RF traces, as the high-frequency substrate coupling can degrade isolation by 5-10 dB relative to the datasheet's 22 dB figure.
