Product Description
Preliminary
Sirenza Microdevices’ SGA-8343 is a high performance Silicon
Germanium Heterostructure Bipolar Transistor (SiGe HBT)
designed for operation from DC to 6 GHz. The SGA-8343 is
optimized for 3V operation but can be biased at 2V for low-voltage
battery operated systems. The device provides high gain, low NF,
and excellent linearity at a low cost. It can be operated at very low
bias currents in applications where high linearity is not required.
Product Features
• Now Available in Lead Free, RoHS
Compliant, & Green Packaging
• DC-6 GHz Operation
• 0.9 dB NFMIN @ 0.9 GHz
• 24 dB Gmax @ 0.9 GHz
The matte tin finish on Sirenza’s lead-free package utilizes a post
annealing process to mitigate tin whisker formation and is RoHS
compliant per EU Directive 2002/95. This package is also
manufactured with green molding compounds that contain no
antimony trioxide nor halogenated fire retardants.
• |GOPT|=0.10 @ 0.9 GHz
• OIP3 = +28 dBm, P1dB = +9 dBm
• Low Cost, High Performance, Versatility

[1] 100% tested - Insertion gain tested using a 50 ohm contact board (no matching circuitry) during final production test.
[2] Sample tested - Samples pulled from each wafer/package lot. Sample test specifications are based on statistical data from sample test measurements. The test fixture is
an engineering application circuit board (parts are pressed down on the circuit board). The application circuit represents a trade-off between the optimal noise match and
input return loss.
