Specifying Crystals for Use in VCXOx and TCXOs for Wireless Designs On GlobalSpec

From Fox Electronics, Inc.

Quartz crystals can be an excellent choice for the frequency-determining component in wireless communication systems. Designers appreciate the high Q value (quality factor), reasonable cost, and temperature performance of quartz crystals relative to other options, such as inductor-capacitor, ceramic, microstrip and surface acoustic wave resonators

RF Filters and Microwave Filters

RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters.

Oscillators

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 Band Pass Filters

RF band pass filters are active or passive circuits that pass signals from a specific frequency band and reject signals from out-of-band frequencies. Surface acoustic wave (SAW) filters, crystal filters, and cavity filters are types of band pass filters.
