Radio frequency/microwave amplifiers (RF/microwave amplifiers) are electronic devices that take in signals with varying input then use a power supply to smoothly alter the current to generate an output signal similar to the input signal, only magnified. When considering RF amplifiers specifications, you must consider output that's dependent on input load, temperatures, power supply and the voltage standing wave ratio (VWSR).

Radio frequency amplifiers, sometimes called a RF amplifier or RF amp, can amplify low noise and power and can also act as a bi-directional amplifier. They come in several different packages and have various connector types including:

1. Surface mount technology (SMT), which is a package type used in products, such as circuit boards, where low-frequency components become high-power microwave amplifiers with increased performance in applications using high frequency.

2. Through hole technology (THT), which is a package type similar to the SMT. THT is sturdier and a bit more complex, since pins hold the components together in the microwave amplifier.

3. Bayonet Neil-Concelman (BNC) connections work as microwave power amplifier connectors used in video and RF applications, which use a slotted outer conductor and a plastic dielectric to increase loss at higher frequencies.

Action Steps
The best contacts and resources to help you get it done

Purchase from a microwave amplifier manufacturer specializing in surface mount technology products

Find RF microwave amplifiers for your business from manufacturers with a history of product quality and innovation. Manufacturers often abbreviate the product name as microwave amp.

I recommend: Avago Technologies offers a variety of SMT products, including its Low Noise Amplifier for wireless applications. It offers quality customer service worldwide and efficient product delivery. MITEQ products have a three-year warranty. Its dedication to customer satisfaction includes updated engineering resources, which allow it to modify original designs to meet customer specifications.

Consider a RF amplifier distributor with a wide range of inventory for THT products

The more products a distributor has, the greater the odds that they have precisely what you are looking for.

I recommend: Teledyne Technologies offers a huge selection of RF amplifier products including THT packages. Digi-Key, a worldwide supplier of RF/microwave amplifiers and other electronic components, offers clients easy, online shopping and a large selection of product, including THT packages.

Find connections for existing RF/microwave amplifiers from knowledgeable manufacturers

When looking for components for a microwave power amplifier, consider consulting with a manufacturer who knows the best type of connector for your purposes, whether it's a BNC, MMCX SMP or other.

I recommend: Emerson Network Power Connectivity Solutions offers products such as Connectors and Adapaters, which work with RF/microwave amplifiers. The company has over 80 years of service, selling numerous products from specified brand names to satisfied customers. Conec offers a wide variety of connectors in addition to custom solutions. It designs and manufactures products for clients.
