Description
The SKY65048-360LF is a high performance, two-stage ultra-low
noise amplifier. The device is fabricated from Skyworks advanced
pHEMT process and is provided in a 2 x 2 mm, 8-pin Quad Flat
No-Lead (QFN) package.
The device features excellent input and output return loss, an
integrated interstage matching network, and integrated source
inductors for 1
st
and 2
nd
stage transistors. The amplifier’s ultra-
low Noise Figure (NF), high gain, and excellent 3
rd
Order Intercept
point (IP3) allow it to be used in various receiver and transmitter
applications.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.
