Description
Skyworks SKY65038-70LF is a general purpose, broadband Low
Noise Amplifier (LNA). The device is fabricated from Skyworks
pHEMT process and packaged in a miniature Small Outline
Transistor (SOT-89) package.
The LNA’s high gain, low noise, and 3
rd
Order Output Intercept
Point (OIP3) allow the SKY65038-70LF to be used a various
transmitter and receiver application. The device’s 50
Ω
output
impedance allows it to be easily cascaded with a simple input
impedance matching network. The typical useable bandwidth of
the SKY65038-70LF is 0.25 to 6.0 GHz.
A functional block diagram is provided in Figure 1. The device
package and pinout are shown in Figure 2.
