RF Microwave oscillator and microwave connector

MIcrowave oscillator:

Oscillator circuits generate periodic electrical signals by converting a fraction of the constant polarity power supply thereto into a periodic signal output without requiring a period signal input. Radio frequency (RF) oscillators are widely used for generating, tracking, cleaning, amplifying, and distributing RF carriers. Microwave oscillators are employed in wireless telecommunication equipment, such as for instance radio links or satellite transponders, as local oscillators for frequency converters. In particular, voltage-controlled oscillators with phase-locked loops are used for clock recovery, carrier recovery, signal modulation and demodulation, and frequency synthesizing. A microwave VCO is a microwave oscillator whose oscillation frequency is controllable by means of a voltage. RF oscillators and modulators typically must meet certain requirements in power and frequency output.

Microwave connector:

Electrical and electronic systems make use of connectors for coupling different portions of the system together. Such connectors are capable of being engaged and disengaged so that the different parts of the system may be separated. Radio frequency (RF) connectors are generally used to connect various components of RF equipment. Such RF connectors interconnect various components including coaxial cable and printed circuit boards. Connectors associated with RF communication systems typically use coaxial transmission line systems to conduct RF signals from one point to another. Coaxial radio frequency cables having hollow center conductors are generally used for many applications including land mobile, microwave broadcast and radar band frequencies. These coaxial transmission line systems employ connectors at their ends to connect the transmission line system to additional coaxial transmission line systems or various RF circuit assemblies. The technological advancement has been calling for broader bandwidths for the radio frequency and microwave equipment. As a result, the RF coaxial connectors, either on the coaxial cable ends or on the PC boards of signal devices, play a more and more important role in signal input and output. The RF connector has an inner conductor and tube-shaped outer conductor, which connect to the respective conductors of the cable. Radio frequency connectors typically comprise a solid, straight center pin, an extruded dielectric material, and a matable housing.
