CBG9008

DESCRIPTION

The CBG9008 is a cascadable, high linearity gain block amplifier in a low-cost surface-mount package. At 1.9 GHz, the 

amplifier typically provides 20.6 dB gain, +36 dBm OIP3, and 1.3 dB Noise Figure while only drawing 85 mA current. The 

device is housed in a leadfree/green/RoHS-compliant industry- standard SOT-89 package using a NiPdAu plating to 

eliminate the possibility of tin whiskering. 

The CBG9008 has the benefit of having high gain across a broad range of frequencies while also providing very low noise. 

This allows the device to be used in both receiver and transmitter chains for high performance systems. The amplifier is 

internally matched using a high performance E-pHEMT process and only requires an external RF choke and 

blocking/bypass capacitors for operation from a single +5V supply. The internal active bias circuit also enables stable 

operation over bias and temperature variations. 

The CBG9008 covers the 0.05-4 GHz frequency band and is targeted for wireless infrastructure or other applications 

requiring high linearity and/or low noise figure.
