µ- strip line
W-band LNA
Typical Assembly and Bias Configuration to increase the
gain :
Let’s tune the value of the external resistor R to control the biasing point of the
first stage and then getting a higher gain for the LNA (trade-off ability between the
gain and the noise factor).
Typical value of the external resistor R :
