What is a Tuner?

An antenna tuner or antenna tuning unit is a device connected between a radio transmitter or receiver and its antenna in order to improve the effectiveness of the power transfer between them. This is done by matching the impedance of the equipment to that of the antenna. A tuner matches a transceiver with a fixed impedance to an unknown, complex or non-matching antenna impedance. An antenna tuning unit allows one antenna to be used for a broad range of frequencies. A tuner is typically connected between the antenna and the radio transmitter or receiver and is more specifically connected between the feed line and the antenna or between the feed line and radio to minimize loss.

Types of Tuners

There are several different kinds of tuners at Future Electronics. We stock many of the most common types categorized by manufacturer name and packaging type. Our parametric filters will allow you to refine your search results according to the required specifications.

Tuners from Future Electronics

Future Electronics has a wide range of tuners from several manufacturers. Once you decide the manufacturer name or packaging type required, your search results will be narrowed to match your specific tuner application needs. You will then be able to find the right tuner chip for your wireless tuner, RF tuner, digital HD TV tuner card, HDTV tuner, audio tuner or TV tuner cards for a laptop or PC computer.

We deal with several manufacturers such as Hittite Microwave, Johanson Manufacturing Corp and NXP. You can easily refine your tuner product search results by clicking your preferred tuner brand from the list of manufacturers below.

Applications for Tuners:

Antenna tuners are used in high power shortwave broadcasting transmitters. This is due to frequent waveband changes. Most antennas that are used in high power shortwave broadcasting are HRS type antennas. In HRS antennas the radiating elements are of a fixed length and the antenna resonance is optimized for one or two bands only.

Choosing the Right Tuner:

With the parametric search, when looking for the right tuner, you can filter the results by the required category and narrow them down by various attributes. You will be able to find the right tuner chip for your digital HD TV tuner card, wireless tuner, audio tuner, RF tuner, HDTV tuner or TV tuner cards for a PC computer or laptop using these filters.

Tuners in Production Ready Packaging or R&D Quantities

If the quantity of tuners you require is less than a full reel, we offer customers several of our tuner devices in tray, tube or individual quantities that will help you avoid unneeded surplus.

Future Electronics also offers clients a unique bonded inventory program designed in order to eliminate potential problems that can arise from an unpredictable supply of products that could contain raw metals and products with erratic or long lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
