3.8 GHz antenna switches/tuners optimise signal paths for wider handset ranges

July 06, 2016 // By Graham Prophet
Skyworks Solutions adds to its antenna tuning product portfolio with devices intended to optimize radiated efficiency, the antenna aperture tuners enable higher data throughput and smaller footprints

Skyworks’ new antenna tuning switches provide low R on for higher efficiency, transfer more power to the antenna, offer low C off to deliver accurate and consistent tuning results, enable high Vpeak for improved radiated spurious emission (RSE) performance and integrate GPIO-control for ease of use. To simplify the design process and accelerate time-to-market, Skyworks assists with antenna modeling, data simulation, design and layout optimization, and onsite support to help customers leverage these advanced antenna tuning products into their platforms. These products are shipped in a RoHS compliant plastic package with compact 10 pin 1.1 x 1.5 x 0.5 mm quad-flat no-leads (QFN). The common footprint of these devices allows customers to utilize one layout across multiple designs.

The SP2T variant listed below offers the following features;

- Broadband frequency range: 0.1 to 3.8 GHz

- Low ON-state resistance and OFF-state capacitance

- High-power and peak-voltage handling (+40 dBm/42V typical)

- No external DC blocking capacitors required

- Small QFN (10-pin, 1.5 x 1.1 x 0.5 mm maximum) package

These new devices are available in the following configurations:
