General Description

The SX1250 is a sub-GHz RF Front End device designed to

work along with Semtech’s SX1302 baseband engine, to

design a high-performing LoRa® or LoRaWAN gateway.

It covers any frequency band below 1 GHz, making it the

perfect candidate to support any license-free band used in

today’s IOT use cases.

The device supports up to +22 dBm output power on-chip.

This embedded high-power capability can be leveraged to

reduce the bill of material cost when designing a gateway.

As far as receiver, the Noise Figure of the system is also

extremely low, eliminating the need for an external

high-end and power-consuming Low Noise amplifier, if the

goal is to come up with a cheaper and median-spec

gateway.

Applications

• LoRa® and LoRaWAN gateways
