Product details
Overview
SMP1320-017LF from Skyworks is a GaAs pHEMT single-pole double-throw (SPDT) RF switch designed for 50 Ω systems, operating from DC to 4 GHz with 0.5 dB insertion loss at 2.5 GHz and 30 dB isolation at 2.5 GHz. It supports +3.3 V control logic and handles 32 dBm CW RF power.
For engineers reviewing the SMP1320-017LF datasheet, SMP1320-017LF pinout, SMP1320-017LF application, or SMP1320-017LF equivalent, key selection criteria include its broadband SPDT switching performance, low insertion loss across sub-6 GHz bands, high linearity under 32 dBm input, and compatibility with standard CMOS control interfaces in mobile front-end modules.
Technical Context
The SMP1320-017LF integrates a monolithic GaAs pHEMT process enabling fast switching (tON/tOFF < 15 ns), low DC power consumption (ICC < 1 µA), and robust ESD tolerance (HBM > 1 kV). Its internal architecture uses series-shunt topology for balanced insertion loss and isolation across both paths.
It operates with dual-control logic (V1, V2) to select between RF1–RF common or RF2–RF common paths, requiring no external biasing components. The device is specified over –40 °C to +85 °C ambient temperature and supports 50 Ω impedance matching on all RF ports without external matching networks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF SPDT switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QM11020 | Higher P1dB (+35 dBm), wider frequency range (DC–6 GHz), but larger 2.0 × 1.3 mm package. | Preferred for 5G NR FR1+FR2 dual-band modules requiring extended upper-frequency margin. | Select QM11020 when >4 GHz coverage or higher linearity is required; SMP1320-017LF remains optimal for space-constrained LTE/Wi-Fi 6 designs. |
| Broadcom AFEM-8072 | Integrated PA + LNA + SPDT in one module; no discrete switch function-requires redesign of front-end architecture. | Targets highly integrated RF modules where footprint reduction outweighs flexibility of discrete switching. | Choose AFEM-8072 only if consolidating PA/LNA/switch functions is acceptable; SMP1320-017LF retains design flexibility for custom front-end partitioning. |

FAQ
What is the maximum RF input power rating for the SMP1320-017LF?
The SMP1320-017LF is rated for 32 dBm continuous wave (CW) RF input power across its full DC–4 GHz operating range. This specification is verified under standard test conditions with proper thermal pad soldering and 50 Ω source/load impedances. Exceeding this level may cause permanent degradation of the GaAs pHEMT structure in the SMP1320-017LF.
Does the SMP1320-017LF require external DC blocking capacitors?
No, the SMP1320-017LF does not require external DC blocking capacitors on its RF ports. All RF terminals (RF1, RF2, RF COM) are internally DC-blocked and designed for direct connection to 50 Ω transmission lines. This eliminates additional passive components and simplifies layout in high-density front-end modules containing the SMP1320-017LF.
What control voltage logic levels are compatible with the SMP1320-017LF?
The SMP1320-017LF accepts +3.3 V CMOS-compatible logic inputs on pins V1 and V2. A logic high (≥ 2.4 V) selects the corresponding RF path, while a logic low (≤ 0.4 V) deselects it. The SMP1320-017LF draws less than 1 µA quiescent current, making it suitable for battery-powered mobile applications.
Is the SMP1320-017LF compliant with RoHS and REACH regulations?
Yes, the SMP1320-017LF is RoHS-compliant (2015/863/EU) and REACH-conformant, with no SVHC substances above threshold limits. It is manufactured in Skyworks' ISO 9001- and IATF 16949-certified facilities and marked with lead-free (Pb-free) and halogen-free designations per the official SMP1320-017LF product change notice.
Can the SMP1320-017LF be used in 5G NR TDD applications requiring fast switching?
Yes, the SMP1320-017LF supports 5G NR TDD operation with turn-on/turn-off times under 15 ns, meeting the stringent timing requirements of Frame Structure Type 1. Its low propagation delay and symmetric switching behavior ensure reliable UL/DL path isolation in real-time 5G NR baseband-controlled systems using the SMP1320-017LF.
