The increasing number of wireless standards and frequency bands has created significant challenges for RF designers. The combination of low voltage operation, high linearity, sensitivity, and high Quality factor (Q) performance coupled with small size makes programmable or tunable RF capacitors, utilizing MEMS, the ideal solution to this growing problem, restoring design margin while improving performance, reducing power consumption and increasing manufacturing yields.
WiSpry’s TDCA product line is a family of digital tunable capacitor arrays targeted at mobile wireless applications. These range from standard 5pF, 10 pF & 20pF arrays up to custom configurations (~30pF +) for higher capacitance values. The tunable capacitors are ideally suited for antenna tuning and impedance matching and as the basis for complex tunable front-end filters for 3G and 4G wireless devices.
WiSpry products deliver exceptional RF performance due to their tunability, high Q-factor performance, and high linearity. As important these substantial performance benefits are provided at equivalent or lower cost and footprint than existing implementations.
WiSpry’s tunable digital capacitors, are manufactured using standard RF CMOS fabrication techniques. Our tiny microscopic capacitor structures, offer the ultimate in tunable RF performance. These miniature RF capacitors operate in a similar way to conventional parallel plate RF capacitors, with the difference being that the plate distance is made dynamically tunable with the help of MEMS technology.
WiSpry’s CMOS process technology permits further integration with active silicon devices, such as transceivers, Low Noise Amplifiers (LNAs) and Power Amplifiers (PAs) This not only reduces size and cost, but also enables new and innovative dynamic RF architectures for next generation handset designs.
