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.
