SKY68031-11

RF Front End (LNA + PA) Overview

The SKY68031-11 is a multi-band RF front-end module designed for LTE-M and NB-IoT applications. It operates within a frequency range of 400 MHz to 2.7 GHz, supporting half-duplex FDD (HD-FDD) transceiver platforms. The device integrates essential components including a power amplifier, low-noise amplifier, and an SP6T switch into a compact 24-MCM (3x3) package. It functions with an operating supply voltage between 2.85 V and 4.5 V and draws a typical operating supply current of 400 nA. The module supports standard delivery periods and is suitable for cellular IoT devices requiring efficient signal processing across multiple bands.

RF Front End (LNA + PA) Procurement Notes

Verify the specific ordering suffix and packaging configuration when placing orders, as distribution channels may list varying reel quantities or tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Ensure that the lead time aligns with production schedules, as standard delivery periods can extend significantly depending on manufacturer capacity. Cross-reference the DigiKey or Mouser part numbers to ensure accurate sourcing from authorized distributors.

RF Front End (LNA + PA) Selection Notes

Select this module for designs requiring integrated support for both LTE-M and NB-IoT standards without separate discrete components. It is ideal for applications prioritizing low power consumption and small footprint over high-throughput data rates. Ensure the host system provides the required 2.85 V to 4.5 V supply rail and matches the thermal management capabilities for the +85 C maximum operating temperature. Verify compatibility with the intended antenna switching architecture given the single SP6T configuration.
