RFMW, Ltd. announces a web based tool that allows designers to create semi-custom Voltage Controlled Oscillators (VCOs) and Phase Locked Loop (PLL) synthesizers. Designers can search a large database of existing products based on parametric requirements and jump directly to existing product information. Should the database not include an exact match, users can define their requirement for an RFMD factory review and feedback. Often, requirements are a simple derivative of existing products. Narrow-band to octave band frequency coverage from product families ranging 10MHz to 8.5GHz. Ultra low phase noise oscillators provide unsurpassed performance in standard and small form factor, surface mount packages.
