Skyworks Solutions Inc. has introduced two miniature 0402 varactor diodes for VCO, phase noise, frequency control and voltage tuned filter applications including WLAN, CATV low noise block, energy management, wireless infrastructure and military devices. These small form factor, low profile plastic surface mount technology packaged diodes offer a discrete solution and are ideal for applications requiring low resistance and low capacitance over a narrow 0 to 5 V range. These general market, miniature diodes offer a reduced footprint and combine both low series resistance and high tuning ratio in an industry-standard package.
