lähetinvastaanotinpiirit, often abbreviated as transceivers, are electronic devices that combine the functions of both a transmitter and a receiver in a single unit. This integration allows for bidirectional communication, meaning information can be sent and received over the same channel. The transmitter section converts electrical signals into radio waves for transmission, while the receiver section converts incoming radio waves back into electrical signals. This duality is crucial for many communication systems.

The core components of a transceiver typically include an oscillator for generating the carrier frequency, a modulator for encoding information onto the carrier, an amplifier for boosting the transmitted signal, a mixer for frequency conversion, a demodulator for extracting information from the received signal, and a filter for selecting the desired frequencies. The design and complexity of these circuits vary greatly depending on the intended application, ranging from simple walkie-talkies to sophisticated telecommunication equipment.

Transceivers are fundamental to a vast array of technologies. They are found in mobile phones, wireless routers, amateur radio equipment, radar systems, and satellite communication devices. Their ability to facilitate two-way communication makes them indispensable for connecting people and devices across distances. The ongoing development in semiconductor technology continues to drive miniaturization, increased efficiency, and enhanced functionality in transceiver designs.
