50 – 6000 MHz
InGaP HBT Gain Block
Data Sheet
Description
Features
Avago Technologies’AVT-55689 is an economical, easy-to- •ꢀ Small signal gain amplifier
use, general purpose InGaP HBT MMIC gain block amplifier
utilizing Darlington pair configuration housed in a 3-lead
(SOT 89) surface mount plastic package.
•ꢀ Operating frequency 50 MHz to 6 GHz
•ꢀ Unconditionally stable
•ꢀ 50 Ohm input & output
The Darlington feedback structure provides inherent
broad bandwidth performance, resulting in useful
operating frequency up to 6 GHz. This is an ideal device
for small-signal gain cascades or IF amplification.
•ꢀ Industry standard SOT-89
•ꢀ Lead-free, RoHS compliant, Green
Specifications
AVT-55689 is fabricated using advanced InGaP HBT
