The MAAL-011181-DIE is a wideband distributed low noise amplifier with an operating frequency range of 9 kHz to 20 GHz. This LNA has a typical 2.5 dB noise figure, 15 dB gain, 29 dBm OIP3, 19 dBm 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. A DC blocking capacitor is required on the RF input. 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-DIE is designed for wideband low noise applications such as test equipment. It is available as a bare die. This LNA is also available in a 5 mm, 32 lead PQFN package under part number MAAL-011181.
