Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices

Circular connectors are multi-pin connectors primarily used for external interfacing

Micro connectors and nano connectors exhibit contact pitches of 0.05'' (micro) and 0.025'' (nano), respectively

DIN connectors are high frequency, multi-pin, electrical connectors that meet standards established by Deutsches Institut für Normung (DIN), a German national organization for standardization. The ends of DIN connectors are round, notched, and protected by a metal skirt to ensure that pins line up correctly

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

RF waveguide components are circular, elliptical or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide

I/Q modulators and I/Q demodulators change the amplitude, frequency, or phase of a carrier signal in order to transmit information. I/Q modulators split an incoming data stream into its in-phase (I) and quadrature (Q) components, mix the resulting signals with local oscillators that are 90º apart in phase, and then combine the outputs vectorially in a 0º mixer.

RF limiters are circuits that prevent the amplitude of a waveform from exceeding a specified value. There are three basic types of RF limiters: conventional, feedback, and high power.

RF switches route radio frequency signals to particular waveguides.

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.

RF diplexers are three-port frequency-dependent devices that may be used as a separator or a combiner of signals. RF duplexers allow a transmitter operating on one frequency and a receiver operating on a different frequency to share a common antenna with a minimum of interaction and degradation of the different RF signals.

Phase-locked loop (PLL) frequency synthesizers are electronic devices that produce frequencies coherent to a reference frequency.

Relay sockets are devices that accept relays, electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit.

Frequency discriminators are RF or microwave devices that are used to detect a signal with a particular frequency.

Resonators are frequency-selective electronic circuits that can produce a fixed (resonant) frequency when properly excited. The value of the resonant frequency depends on the circuit’s components (e.g., inductors, resistors, capacitors, crystals, etc.).
