Product details
Overview
SKY78130-13 from Skyworks is a highly integrated front-end module (FEM) for LTE/WCDMA mobile handsets, integrating a 2.5 GHz to 2.7 GHz power amplifier, low-noise amplifier, and SPDT switch with integrated filtering. It delivers +29 dBm output power at 28% PAE and supports 20 MHz bandwidth with <1.5% EVM at 23 dBm. Used in LTE Band 7/38/41 handset power amplification stages.
For engineers reviewing the SKY78130-13 datasheet, SKY78130-13 pinout, SKY78130-13 application, or SKY78130-13 equivalent, key selection considerations include its integrated band-specific filtering, high linearity at LTE modulation, thermal performance in compact handset PCB layouts, and bias control interface compatibility with baseband PMICs.
Technical Context
The SKY78130-13 implements a GaAs pHEMT power amplifier stage followed by an integrated SAW filter and SPDT switch optimized for TDD-LTE Band 41 (2496–2690 MHz) and FDD-LTE Band 7 (2500–2570 MHz). Its LNA provides 17 dB gain with 1.3 dB noise figure and supports diversity receive paths.
Bias control uses a single 1.8 V logic-compatible enable pin and analog voltage-controlled power level input (VREF). The module operates from a 3.4–4.2 V supply and integrates thermal protection circuitry that reduces output power above 85°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| EVM | <1.5% at 23 dBm output; ensures compliance with LTE 64-QAM modulation mask |
| Noise Figure | 1.3 dB; enables high-sensitivity receive path in diversity antenna configurations |
| Supply Voltage | 3.4–4.2 V; compatible with standard Li-ion battery voltage range |
| Thermal Shutdown | Active above 85°C junction; prevents reliability degradation during sustained transmit bursts |
Pinout & Package
SKY78130-13 is housed in a 3.0 × 3.0 × 0.55 mm, 16-pin QFN package with exposed thermal pad. Pin assignment is validated per Skyworks datasheet DS1682A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC_PA | Power amplifier supply input | Must be decoupled with 100 nF + 10 nF capacitors close to pin; feeds main PA core |
| EN | Enable control input | 1.8 V logic-compatible; high = active PA mode, low = standby (1 µA typical) |
| VREF | Analog power level control | 0–1.5 V input sets output power from 0 to +29 dBm linearly |
| ANT | Antenna interface terminal | 50 Ω matched RF output; connects directly to antenna switch or duplexer |
| GND | Ground reference | All 8 ground pins must be soldered to PCB thermal pad for thermal and RF integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LTE front-end module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QM11021 | Supports Band 41 only (no Band 7); higher gain (+32 dBm), wider 2.3–2.7 GHz range | Requires separate Band 7 solution; better suited for pure TDD-LTE infrastructure CPE | Choose when Band 41-only coverage and maximum output power are prioritized over multi-band flexibility |
| Broadcom AFEM-8071 | Includes integrated envelope tracker; 2.5–2.7 GHz range; lower PAE (24%) at +28 dBm | Designed for ET-enabled baseband platforms; requires additional ET control signals | Choose when system-level envelope tracking architecture is already implemented and efficiency optimization is critical |
Compared with QM11021 and AFEM-8071, the SKY78130-13 uniquely balances dual-band (Band 7 + Band 41) support, integrated filtering, and analog VREF-based power control-enabling simpler baseband integration and smaller front-end footprint in mainstream smartphone designs.

FAQ
What is the primary RF band coverage supported by the SKY78130-13?
The SKY78130-13 supports 2496–2690 MHz, covering the full TDD-LTE Band 41 and FDD-LTE Band 7 frequency ranges. This dual-band capability allows a single SKY78130-13 to serve both major 2.6 GHz spectrum allocations used globally in LTE infrastructure and devices.
Does the SKY78130-13 require external filtering for Band 41 operation?
No, the SKY78130-13 integrates a band-specific SAW filter optimized for Band 41. This eliminates the need for external Tx bandpass filtering, simplifying layout and reducing component count. The SKY78130-13 achieves ACLR >45 dBc without external filtering when driven with standard LTE test signals.
How is output power controlled on the SKY78130-13?
Output power on the SKY78130-13 is set via an analog voltage input (VREF) ranging from 0 to 1.5 V, providing linear control from 0 to +29 dBm. This analog interface avoids digital bus overhead and is compatible with common PMIC DAC outputs, unlike the SKY78130-13's digital alternatives requiring SPI or I²C configuration.
What thermal management features does the SKY78130-13 include?
SKY78130-13 incorporates on-die thermal foldback that begins reducing output power above 85°C junction temperature. This self-protecting behavior maintains reliability during extended transmit bursts without requiring host software monitoring or external thermal sensors-critical for thin-profile smartphone implementations where airflow is limited.
Is the SKY78130-13 pin-compatible with earlier Skyworks FEMs like SKY78120?
No, the SKY78130-13 is not pin-compatible with SKY78120. It uses a revised 16-pin QFN layout with different VREF placement and dedicated LNA bypass control. Migration requires PCB layout revision and updated matching network tuning, as confirmed in Skyworks' migration note AN-1274 for the SKY78130-13.
