868.3 MHz FM Superheterodyne Receiver Module

High-sensitivity, high-selectivity FM superheterodyne receiver with a front-end SAW filter that makes it highly immune to interference

SKU 8110-RX-FM8SF868EAN 8219671044868Item type: Assembled

Description

High-sensitivity and high-selectivity FM superheterodyne receiver, featuring a front-end SAW filter that makes it highly immune to interference. Thanks to the enable pin, the receiver can enter power-down state in the absence of a signal, minimizing consumption to 0.5 μA. Ideal for Microchip Keeloq encoding.
