General Description
The TriQuint TGM2543-SM is a combination limit-
er/LNA which provides 4W CW survivability, 17 dB
mid-band gain, and 2 dB mid-band noise figure,
with operation across 4-20 GHz. This product fea-
tures adjustable gain and uses a high performance
ceramic package. The TGM2543-SM limiter is de-
signed using TriQuint’s proven standard GaAs
VPIN product process, and the LNA function is fab-
ricated with the GaAs pHEMT 0.15μm gate produc-
tion process.
The TGM2543-SM features flat gain and low noise
figure in a hermetically sealed ceramic QFN de-
signed for surface mount to a printed circuit board.
Fully matched to 50 ohms and with integrated DC
blocking capacitors on both I/O ports, the
TGM2543-SM is ideally suited to support both com-
mercial and defense related applications
Lead-free and RoHS compliant.
Evaluation Boards are available upon request.
