Sky Works

skyworks solutions' metal-insulator-semiconductor (mis) chip capacitors are available in a wide range of capacitance values and die sizes for chip-and-wire circuits requiring dc blocking, rf bypassing or as tuning elements in filters, oscillators and matching networks.

the capacitors have a dielectric composed of thermally-grown silicon dioxide over which a layer of silicon nitride is deposited. This two-layer dielectric produces a very a low temperature coefficient of capacitance, very high insulation resistance, outstanding long-term stability and excellent reliability. The temperature coefficient of capacitance is less that 50 ppm/°c, and the capacitors are suitable for operation from -65 °c to 200 °c. Skyworks mis chip capacitors offer very high q.

wafers can be supplied on expanded film frame for automatic pick-and-place manufacturing. To reduce cost, chips can be supplied packaged in vials with sample electrical testing. Packaging in waffle packs with 100% electrical test and visual inspection is available if required.

The AA103-72 is a 1 bit GaAs IC FET digital attenuator in a low cost package. This attenuator has an LSB of 10 dB. The AA103-72 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required.Typical applications include cellular radio, wireless data, and wireless local loop gain level control circuits.

The AA105-86 is a 4 bit, single positive control GaAs IC FET digital attenuator. It requires DC blocking capacitors, positive supply voltage (VS) and four individual positive bit control voltages (V1–V4). The AA105-86 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include cellular radio, wireless data, and wireless local loop gain level control circuits.

The AA107-310 is a GaAs FET IC 5-bit digital attenuator with a serial-to-parallel driver packaged in a 32-leadless exposed pad plastic package. It is particularly suited at IF frequencies where high attenuation accuracy, low insertion loss, and low intermodulation products are required. Typical applications include base station, wireless and RF data and wireless local loop gain control circuits.

The AS179-000 is a monolithic SPDT switch, fabricated using Skyworks proprietary GaAs PHEMTs as the switching elements. This wideband switch operates with RF signals from 300 kHz–3 GHz. The RF signal paths within the AS179-000 are bilateral. The J1 and J2 RF input/output terminals are reflective.

The ATN3580 series of attenuator chips incorporate thin film resistors on high resistivity silicon chips to achieve precision attenuation, tight flatness and high return loss to 40 GHz. The design uses a balanced TEE resistive structure to assure broad bandwidth performance. The thin film technology offers improved power handling capability in comparison to the traditional thick film printed attenuator. All ATN3580 attenuator chips are specified for their attenuation at DC. In addition, a wafer probe sample test is performed to 40 GHz to assure meeting the flatness specification. Skyworks' measurements indicate that attenuation typically increases with increasing frequency, as shown in Figure 1.

skyworks series of packaged, beam-lead and chip zero bias schottky barrier detector diodes are designed for applications through k band. The choice of barrier metal and process techniques results in a diode with a wide selection of video impedance ranges.

the packaged diodes are suitable for use in waveguide, coaxial and stripline applications. The beam-lead and chip diodes can also be mounted in a variety of packages.

unmounted beam-lead diodes are especially well suited for use in mic applications. Mounted beam-lead diodes can be easily used in mic, stripline and other such circuitry.

a complete line of chips is shown for those mic applications where the chip and wire approach is more desirable.
