Amplifiers

RF Component AmplifiersAmplifiers
Amplifiers are used in various functions within a radio subsystem. Used as Low noise amplifiers (LNA's), IF gain stages, or Power Amplifiers (PA's), the purpose of the Amplifier in an RF subsystem remains to increase the link budget and increase the transmission range of a device. Amplifiers can be made from Silicon, but for low noise introduction, high-amplification operation other processes are commonly used, such as HEMT and GaAs.

Modulators

Modulators and DemodulatorsModulators and demodulators are used to change (Modulate) a waveform so that it may carry a signal to the receiving device to be demodulated, whether the signal is voice or data, various techniques are available such as analog modulation (AM, FM) and Digital Modulation (FSK, ASK, PSK etc).

PLLs and Synthesizers are used to generate a frequency from a fixed oscillator frequency or other fixed source.

Filters

Abracon SAW FilterFilters
RF Filters are components utilized to "filter" a frequency. Filter types available include Band pass (i.e. allow a Frequency band to pass through the filter), Low pass (i.e. allow Frequency below a level to pass), and High pass (i.e. allow a frequency above a level to pass through), in certain technologies such as Ceramic and SAW (Surface acoustic Wave).

Mixers

Linear Tech Mixer 10MHz-4GHzMixers
RF Mixers are designed to mix two or more input frequencies and provide either a summed output or a difference output. The original input frequencies may also be output but are typically filtered out in later stages of the application.

Switches

Analog Devices Switch ICSwitches
A switch in RF is used to provide a way to provide a single transmission path in an application where multiple transmission paths are needed. An example would be creating a transceiver out of a receiving device and a transmitting device, creating a single path to the antenna while being able to switch between the receive and transmit paths. Other applications can also include using a single antenna for multiple frequencies or allowing two devices operating at the same frequency to "share" the antenna.
