Antennas are structures or devices used to collect or radiate electromagnetic waves

Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function.

Microwave tubes are lamps that produce microwaves.

RF waveguide amplifiers accept a varying input signal and produce an output signal that varies in the same way, but with a larger amplitude.

Fiber optic amplifiers re-amplify an attenuated signal without converting the signal into electrical form.

Microscopes are instruments that produce magnified images of small objects

Zener diodes are PN junction devices that are designed to operate in the reverse-breakdown region.  

RF waveguide couplers are RF circuits used to sample RF frequency transmissions by coupling (combining) signals asymmetrically.

Flow transmitters provide electrical outputs that are proportional to flow inputs. They use flow meters to measure the flow of liquids and gases.

Wave washers or wave springs are wavy metal washers designed to provide a compensating spring force and sustain a load or absorb shock

Solders include low melting point metal alloys usually in wire, powder, preform or paste forms. Solders are metal alloys with low melting points that are used to join metals together.

Soldering irons, stations and accessories bond two or more metallic surfaces together with a low melting alloy solder such as tin/lead or Sn/Cu/Ni/Ge alloys, which is melted, wets the surface and resolidifies forming a soldered joint.

Waveplates and retardation plates are optical elements with two principal axes, one slow and one fast, which resolve an incident polarized beam into two mutually perpendicular polarized beams. The emerging beam recombines to form

Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs

Rectifier diodes are designed for use in rectification circuits. Rectifiers are used to convert AC to DC.
