Product Detail

Broadband Low Noise Amplifier

 The MAAM-011229-CQ3 is a broadband high dynamic range, single stage MMIC LNA assembled in a lead-free 3 mm 12 lead ceramic QFN package. The amplifier is internally matched to provide flat gain and excellent return losses to 3.25 GHz without any external matching components. Use of external matching could extend usable frequency range beyond 4 GHz. This low noise amplifier has an integrated active bias circuit allowing direct connection to 3 V or 5 V bias and minimizing variations over temperature and process. The bias current can be adjusted with an optional external resistor, so the user can customize the power consumption to fit the application. IADJ pin can be utilized as an enable pin to power the device up and down during operation
