This paper presents a module for a 300-GHz, 20-Gbps amplitude-shift keying (ASK) transmitter using monolithic microwave integrated circuits (MMICs) based on 80- ...

This paper presents new architecture elements for 5G RF front end modules. Circuit details and measurements are presented for coexistence of 5G bands for multiple 4G/5G transmitters.

Parts: Board (PCB) Link ESP32 Link RXB6 433 MHz receiver Link SN65HVD230 Link D24V10F5 Link Buzzer Link Resistor 3,3 KOhm Link Transistor BC547 Link Connector 2-pin Link For programming: 433MHz ...

Due to the non-ideal filtering in the transmitter module the occupied bandwidth is ~200 kHz, so Wenet is not suitable for operation in the 434 MHz ISM band. The usual transmit power we use is 50mW, ...
