What is a Transmitter IC?

A transmitter (or radio transmitter) is an electronic device which produces radio waves with the help of an antenna. A transmitter generates a radio frequency current applied to the antenna, which in turn radiates radio waves. A transmitter generates radio waves for communication, radar and navigational purposes. A transmitter can either be a separate piece of electronic equipment or an integrated circuit (IC) within another electronic device. Most transmitters are used for radio communication of information over a certain distance. The information that is provided to the transmitter is in the form of an electronic signal. This includes audio from a microphone, video from a TV camera, or a digital signal for wireless networking devices. The transmitter combines the information signal that is to be carried with the RF signal which generates the radio waves (the carrier). This is called modulation. In an FM transmitter, the information is added to the radio signal by slightly varying the radio signal's frequency. In an AM transmitter, it is added by varying its amplitude. Several other types of modulation are also used. ICs, or integrated circuits, allow high performance circuits to be built at lesser costs and with significant amounts of space savings.

Types of Transmitter ICs

There are several different kinds of transmitter ICs. At Future Electronics we stock many of the most common types categorized by data rate, supply current, supply voltage, frequency range, packaging type and output power. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for output power are -12 to +10 dBm, -12 to +11 dBm and 10 dBm. We also carry transmitter ICs with output power up to 17 dBm. Frequncy can range from 50 MHz to 950 MHz, with the most common sizes being 290 to 350 MHz and 380 to 450 MHz.

Transmitter ICs from Future Electronics

Future Electronics has a complete selection of transmitter ICs from several manufacturers that can be used for a radio frequency transmitter module or circuits such as a wireless audio transmitter IC, RF transmitter IC, AM or FM radio transmitter circuit, wireless TV transmitter, high power or low power FM transmitter, RFID transmitter, long range FM transmitter, video transmitter, digital FM transmitter or RF transmitter chip. Simply choose from the transmitter IC technical attributes below and your search results will quickly be narrowed in order to match your specific transmitter IC application needs.

If you have a preferred brand, we deal with several manufacturers such as Linx Technologies, Melexis, Micrel Semiconductor, ROHM Semiconductor and NXP, among others. You can easily refine your transmitter IC product search results by clicking your preferred transmitter IC brand below from our list of manufacturers.

Applications for Transmitter ICs:

Transmitters are used in broadcasting applications such as in a radio transmitter or TV transmitter. Transmitters can also be found in electronic devices that communicate by radio including cell phones, wireless computer networks, garage door openers, Bluetooth devices, two-way radios in ships, aircraft, and spacecraft, navigational beacons and radar sets. The antenna can be enclosed inside the case or attached to the outside of the transmitter, as in portable devices including cell phones, walkie-talkies, and auto keyless remotes. For more powerful transmitters, the antenna may be located on top of a building and connected to the transmitter by a transmission line.

Choosing the Right Transmitter IC:

When you are looking for the right transmitter ICs, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Data Rate (9.375 kbps, 40 kbps, 153.6 kbps , …), Supply Voltage (1.8 V to 5.5 V) and Frequency Range (from 50 MHz to 950 MHz) to name a few. You will be able to find the right transmitter IC that can be used for a radio frequency transmitter module or circuits such as a wireless audio transmitter IC, wireless TV transmitter, high power or low power FM transmitter, RF transmitter IC, AM or FM radio transmitter circuit, long range FM transmitter, digital FM transmitter, RFID transmitter, video transmitter or RF transmitter chip.

Transmitter ICs in Production Ready Packaging or R&D Quantities

If the quantity of transmitter ICs required is less than a full reel, we offer to customers many of our programmable transmitter IC products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers its clients a unique bonded inventory program designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times.
