AVT-55689
50 – 6000 MHz
InGaP HBT Gain Block
Data Sheet
Description
Avago Technologies’ AVT-55689 is an economical, easy-to-
use, general purpose InGaP HBT MMIC gain block amplifier
utilizing Darlington pair configuration housed in a 3-lead
(SOT 89) surface mount plastic package.
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.
AVT-55689 is fabricated using advanced InGaP HBT
(hetero-junction Bipolar Transistor) technology that
offering state-of-the-art reliability, temperature stability
and performance consistency.
