Distributed Low Noise Amplifier 9 kHz - 20 GHz

The MAAL-011181 is a wideband distributed low noise amplifier with an operating frequency range of 9 kHz to 20 GHz. This LNA typically has a 2.5 dB noise figure, 15 dB gain, 29 dBm output IP3, 19 dBm output P1dB, and 21 dBm P3dB. Only a single bias supply voltage of 5 V is required to bias the LNA. The typical current draw is 125 mA.

No external matching components are required, but external biasing components are needed. Large capacitors for bypassing are required on CBIAS1 and CBIAS2 for low frequency operation. An RF choke and blocking capacitor should be added to the RF output pin to bias the amplifier. 5 V must be applied to VBIAS while VDD can vary.

The MAAL-011181 is designed for wideband low noise applications such as test equipment. The 5 mm, 32 lead PQFN package is lead free and RoHS compliant. This LNA is also available in die form under part number MAAL-011181-DIE.
