Introduction

JR2305 is a low-power, high-performance, plug-and-play OOK RF receiver. The device features a wide input voltage range of 2.5V to 5.5V, sensitivity up to -109dBm, operating frequency range of 300–480MHz, and supports data rates from 1 to 5Kbps. Housed in a SOP-8 package, the application circuit requires only an antenna impedance matching network, VDD decoupling capacitor, and AGC filter capacitor — no overshoot protection resistor is needed on the VDD line, reducing overall application cost.
