Product details
Overview
HY92-12LF from Skyworks Solutions is a monolithic 90-degree hybrid coupler designed for RF power splitting and combining in the 0.88–0.96 GHz band, featuring 0.5 dB typical insertion loss, 25 dB typical isolation, ±0.8 dB amplitude balance, ±2° phase balance, and SOIC-8 surface-mount packaging. It serves as a passive divider/coupler in cellular infrastructure transceivers requiring precise quadrature signal distribution.
For engineers reviewing the HY92-12LF datasheet, HY92-12LF pinout, HY92-12LF application, or HY92-12LF equivalent, key selection criteria include its guaranteed 0.88–0.96 GHz bandwidth, 4 W input power handling, RoHS-compliant lead-free construction, and symmetric 4-port configuration enabling flexible port assignment in RF front-end designs.
Technical Context
This device implements a passive, monolithic 90° hybrid architecture with no active components, delivering fixed-phase quadrature outputs between coupled and direct ports. Its performance is specified at 50 Ω impedance and 25 °C ambient, with all ports exhibiting matched VSWR ≤1.2:1 across the band.
The HY92-12LF supports bidirectional operation due to inherent symmetry: any non-ground pin (1, 4, 5, or 8) may serve as input, with corresponding termination and output assignments defined per the datasheet's port mapping table. Ground pins (2, 3, 6, 7) are internally connected and must be soldered to PCB ground planes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.88–0.96 GHz: Full specification compliance across entire cellular UMTS Band IX / LTE Band 8 transmit window. |
| Insertion Loss | 0.5 dB typ.: Represents net path loss from input to direct port, excluding 3 dB theoretical split loss. |
| Isolation | 25 dB typ.: Minimum signal rejection between input and isolated port, critical for transmitter leakage suppression. |
| Amplitude Balance | ±0.8 dB max.: Tolerance between direct and coupled output power levels, enabling accurate I/Q signal generation. |
| Phase Balance | ±2° max.: Deviation from ideal 90° quadrature between coupled and direct outputs, limiting image rejection in modulators. |
| Input Power | 4 W max.: Continuous RF power handling capability without degradation, supporting high-efficiency PA output stages. |
| VSWR (All Ports) | 1.2:1 max.: Ensures <10% reflected power at each port under matched 50 Ω conditions. |
Pinout & Package
HY92-12LF uses an SOIC-8 surface-mount package (5.00 × 4.00 mm footprint, 1.24 mm body height) with gull-wing leads and MSL-1 moisture sensitivity rating. All ground pins are internally tied and require external PCB grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | Primary RF signal entry point; may be reassigned as direct or coupled output per symmetric configuration. |
| 2 | GND | Internally connected ground terminal; must be soldered to PCB ground plane for thermal and RF stability. |
| 3 | ISOL. | Isolated port requiring 50 Ω termination to absorb reflected energy and maintain isolation spec. |
| 4 | GND | Internally connected ground terminal; identical function and connectivity to Pin 2. |
| 5 | Direct | Main output port with 0° phase relative to input; used for carrier or LO paths in quadrature architectures. |
| 6 | GND | Internally connected ground terminal; identical function and connectivity to Pins 2 and 4. |
| 7 | GND | Internally connected ground terminal; fourth ground connection for low-inductance RF return path. |
| 8 | Coupled | Quadrature output port with 90° phase shift; paired with Pin 5 for I/Q signal generation or antenna diversity switching. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Cellular Base Station Transceivers | UMTS/LTE Power Amplifier Feedback |
|---|---|

IC Role / Device Role / Timing Role: Signal splitter routing common IF/RF source to two parallel receiver paths with matched group delay. Use Value: ±0.8 dB amplitude balance maintains consistent SNR across diversity branches, improving fade margin by ≥3 dB. | Use Scenario: Reference signal distribution in automated RF test fixtures verifying transceiver EVM and spectral mask compliance. IC Role / Device Role / Timing Role: Precision power splitter delivering phase-coherent stimulus signals to multiple DUT inputs simultaneously. Use Value: 1.2:1 VSWR across all ports ensures minimal mismatch uncertainty (<0.1 dB) in calibrated measurement setups. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 90-degree hybrid coupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QPB9050 | 0.7–1.0 GHz range; 0.6 dB insertion loss; SOIC-8; requires external 50 Ω termination on isolated port. | Broader bandwidth but looser phase balance (±3.5°), less suitable for high-accuracy I/Q modulation. | Select when wider frequency coverage is prioritized over quadrature fidelity in non-critical feedback paths. |
| Analog Devices ADL5572 | 0.8–1.0 GHz; integrated active amplifier; 16-QFN package; +5 V supply required. | Active gain (+13 dB) replaces passive loss, but introduces noise figure penalty and DC power dependency. | Select only when system-level gain budget is insufficient to tolerate 3.5 dB passive split loss. |
Compared with QPB9050 and ADL5572, the HY92-12LF delivers superior phase accuracy and zero power consumption in a drop-in SOIC-8 footprint, making it optimal for passive RF signal routing where quadrature integrity and thermal stability are primary design constraints.

FAQ
What is the maximum RF input power rating for HY92-12LF?
The HY92-12LF has an absolute maximum input power rating of 4 W continuous RF power, verified under 25 °C ambient and 50 Ω matched conditions. Exceeding this limit risks irreversible damage to the monolithic passive structure. Derating is recommended above 25 °C per the device's thermal resistance profile, and actual system-level power handling must account for VSWR-induced standing waves at the input port.
Can HY92-12LF be used as both a splitter and a combiner?
Yes, the HY92-12LF operates bidirectionally due to its symmetric monolithic architecture. When used as a combiner, applying equal-amplitude, 90°-phase-shifted signals to the Direct (Pin 5) and Coupled (Pin 8) ports produces a summed output at Pin 1, while Pin 3 must remain terminated. Performance metrics-including isolation and amplitude balance-remain valid in reverse operation per the datasheet's port mapping table.
Does HY92-12LF require external bias or control signals?
No, the HY92-12LF is a fully passive monolithic device with no DC power connections, control pins, or bias circuitry. It functions solely through distributed RF coupling and requires only proper 50 Ω terminations on all ports except the intended input and outputs. This eliminates power supply design complexity and enables operation across extreme temperature ranges (–40 °C to +85 °C).
What is the significance of the "LF" suffix in HY92-12LF?
The "LF" suffix in HY92-12LF denotes lead-free and RoHS-compliant construction per JEDEC J-STD-020 MSL-1 standards, with peak reflow tolerance up to 260 °C. It distinguishes this variant from legacy leaded versions and confirms compliance with environmental regulations for commercial and industrial electronics manufacturing.
How does the SOIC-8 package of HY92-12LF impact PCB layout?
The HY92-12LF's SOIC-8 footprint (5.00 × 4.00 mm) requires strict adherence to Skyworks' recommended board layout: solid ground plane beneath the device, 12 thermal vias under the exposed pad area (Pins 2/3/4/6/7), and controlled-impedance 50 Ω traces with minimized stub length. Deviations increase VSWR and degrade amplitude/phase balance beyond datasheet limits.
