Description

The MAAL-011134 is a high dynamic range, single

stage MMIC LNA assembled in a lead-free 2 mm

8-LD PDFN plastic package. This amplifier has ultra

low noise figure, high gain and excellent linearity. In

the 50 Ω environment and at 3 V, this device offers

less than 0.5 dB noise figure at 2.4 GHz, with 24 dB

of gain and over 33 dBm OIP3.

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 is set by an external

resistor, so the user can customize the power

utilized as an enable pin to power the device up and

down during operation.

This MAAL-011134 is ideally suited for 802.11

multimode applications at 2.4 GHz and 5.8 GHz.

The high gain, low noise figure and fast switching

speed make it ideal for 4 x 4 MIMO 802.11ac

applications.
