Overview
The SKY65017-70LF is a general-purpose, broadband amplifier manufactured by Skyworks Solutions Inc. This device is fabricated using Skyworks' InGaP HBT (Heterojunction Bipolar Transistor) process and is packaged in a miniature SOT-89 (4-pin, 1.5 x 4.0 mm) package. The amplifier is designed for ease of use, with 50 Ω nominal input and output impedance, allowing it to be easily cascaded without external impedance matching networks. It is part of Skyworks' GreenTM product line, which ensures compliance with all applicable legislation and is halogen-free.
