SKY67151: Why so useful?

Superior NF: Evaluation board NF values from 0.25 dB at 900 MHz enable industry leading NF performance for both single-stage and multi-stage LNA architectures

Broad Tuning Range: High performance tunes from 500-3800 MHz with bandwidths of 20% or more allow for high levels of re-use.

Flexible Biasing: Wide range of supply voltages and quiescent currents allow for customization over a wide range of linearity requirements to achieve optimal efficiency.

Let’s take a closer look at some measured data…

Note the flat NF response above 45 mA with superior NF down to 20 mA. The device current can be set independently from Vdd which can be set anywhere from 2.7 to 6 volts. This flexible biasing capability results in a device which can be used for a wide range of applications.

In addition to its broad tuning range and biasing flexibility, the SKY67151 displays outstanding RF performance and reliability at temperatures up to +105C. In fact, all the members of Skyworks’ high performance LNA families exhibit excellent thermal performance.

The IP3 response of an amplifier shows a dependency on matching as well as bias conditions and the SKY67151 is no exception. This ability to set Iddq independent of the Vdd provides application flexibility to the designer who wants fully optimize a design. Again, this is just another example of the powerful application flexibility of the SKY67151.
