Our fixed frequency design experience is based around ceramic and dielectric resonator oscillators realized on softboard or alumina circuits. These often incorporate output buffer amplifiers and filters to provide sufficient output power and harmonic suppression. Our oscillators are usually incorporated into more complex modules.

Linwave also has access to synthesizer design expertise including both frequency and phase locking techniques. Most of our synthesizer experience has used VCO frequencies up to 10GHz. These synthesizers can incorporate vibration isolated sources for reduced phase noise degradation and phase hits in the field. Outputs are generally buffered and filtered to provide the necessary output power and harmonic suppression.

Linwave have two methods of measuring phase noise. A fast delay line discriminator based measurement system from Aeroflex RDL (NTS1000B) which is particularly useful in production, and a more accurate but slower phase detector based system from Agilent (E5501B). This gives us the capability to measure phase noise up to 26GHz.
