The ST17H25 with RF Transceiver ICs TQFN32 RoHS is an integrated radiofrequency (RF) transceiver IC manufactured by Lenze. It is a 32-pin thin quad flat no-lead (TQFN) package, compliant with RoHS standards. This IC integrates a power amplifier, a direct-conversion RF transmitter, an RF receiver, and a baseband control logic circuitry, allowing for communication over short ranges of up to around 1,200 meters. The device is designed for use in compact, low-power systems, such as short-range radio communication systems, security systems, wireless sensing, and point-to-point links. It supports protocols like Bluetooth Low Energy, appropriate for applications ranging from asset tracking to wireless building automation.
