Resonators are frequency-selective electronic circuits that can produce a fixed (resonant) frequency when properly excited.

Oscillators are devices that are used to generate repetitive signals.

Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency.

Ceramic capacitors have a dielectric made of ceramic materials.

RF and microwave laminates are used as substrates for radio frequency (RF) and microwave communication systems and electronics.

Quadrature phase shift keying (QPSK) modulators and binary phase shift keying (BPSK) modulators are used to change certain characteristics (amplitude, frequency or phase) of a carrier signal in order to transmit information.

Military (MIL-SPEC) connectors are built in accordance with military specifications.
