Skyworks Solutions Inc. SKY13348-374LF

Overview

SKY13348-374LF from Skyworks Solutions Inc. is a 0.5GHz to 6.0GHz pHEMT GaAs single-pole double-throw RF switch with 50Ω terminated outputs. The device provides low insertion loss, high isolation, high linearity, and compact MLPD packaging for WiMAX, WLAN, LTE, and other RF switching applications requiring controlled impedance and stable RF performance.

As part of the Skyworks RF switch portfolio, SKY13348-374LF combines 50Ω off-port termination, +37dBm IP1dB performance, low 0.6dB typical insertion loss at 2.5GHz, and high 27dB typical isolation at 2.5GHz in a 1.5mm × 1.5mm 6-pin package. For engineers reviewing the SKY13348-374LF datasheet, SKY13348-374LF pinout, SKY13348-374LF application, or SKY13348-374LF equivalent, this device is widely used in WLAN 802.11 a/b/g/n systems, WiMAX 802.16 modules, LTE RF front ends, dual-band wireless equipment, RF signal routing, and compact communication platforms.

Technical Context

In RF front-end systems, SKY13348-374LF operates as a terminated SPDT switch that routes the common RF port, RFC, to either J1 or J2 depending on the control logic applied to V1 and V2. The non-selected RF output is internally terminated to 50Ω, which helps reduce unwanted reflections and improves RF port behavior in switching systems.

The device uses an advanced 0.5µm GaAs pHEMT process and is designed for medium- to high-power RF switching. Its low insertion loss and high isolation support 2.4GHz, 3.5GHz, and 5GHz wireless paths where RF efficiency, isolation, EVM, harmonic performance, and linearity directly affect system performance.

SKY13348-374LF requires DC blocking capacitors on all RF ports. The external blocking capacitors influence the lower-frequency return loss and insertion-loss behavior, while the off-port termination behavior is defined by the internal switch architecture. Normal switching operation uses complementary V1/V2 logic states; both-high or both-low control states are undefined and should be avoided in production operation.

Key Specifications

Pinout & Package

The SKY13348-374LF pinout uses a compact 6-pin MLPD package with RFC as the common RF input, J1 and J2 as switched RF outputs, V1 and V2 as control-voltage inputs, and GND as the RF and package ground reference. The RF ports must be DC blocked in the final circuit.

For PCB implementation, the RF traces should be laid out as controlled-impedance 50Ω transmission lines. The device should be placed close to the RF path, with short matching routes, low-inductance ground connections, appropriate DC blocking capacitors, and careful separation between RF lines and digital control routing.

Applications

Equivalent & Alternatives

When evaluating SKY13348-374LF equivalent devices, engineers should compare frequency range, insertion loss, isolation, IP1dB, IIP3, off-port termination behavior, control voltage range, RF port capacitance requirements, package size, and WLAN or WiMAX linearity targets.

Compared with SKY13317-373LF, SKY13348-374LF is optimized for 0.5GHz to 6.0GHz RF switching with 50Ω terminated outputs and strong WLAN/WiMAX linearity performance. SKY13348-374LF vs ADG918 selection depends on RF architecture, insertion-loss target, isolation requirement, power handling, control voltage, package constraints, and off-port termination needs.

Quality

SKY13348-374LF should be sourced as original Skyworks Solutions components through traceable and controlled supply channels. Quality verification procedures may include package inspection, top-mark validation, solderability testing, RF insertion-loss verification, isolation measurement, control-voltage switching checks, return-loss testing, and incoming inspection according to RF module production requirements.

Because the device operates in high-frequency RF paths, controlled-impedance routing, DC blocking capacitor selection, low-inductance grounding, RF layout symmetry, ESD handling, and careful isolation from noisy digital traces help maintain insertion loss, return loss, and isolation performance. Traceable sourcing supports wireless-system manufacturing quality and reduces counterfeit supply-chain risk.
