MACOM Introduces New Ultra Low Phase Noise Amplifier

MACOM has added a new wideband, ultra-low phase noise amplifier to its portfolio. The new MAAL-011151 operates from 2 to 18 GHz and is ideally suited for use as a low phase noise amplifier stage for signal generation applications spanning a host of system designs targeting test and measurement (T&M), EW, ECM, and radar.

Phase noise is a critical specification in defining the frequency stability of a signal source, with significant implications for receiver sensitivity performance. MACOM’s MAAL-011151 minimizes phase noise contribution in providing LO signal gain, enhancing spectral integrity for T&M and communications systems, target acquisition for radar, and aerospace and defense (A&D) applications. It will provide 16 dB of linear gain across the 2 to 18 GHz frequency band, 17.5 dBm of P1dB and 5 dB of noise figure at 10 GHz with input and outputs that are fully matched to 50 Ω and are DC blocked. Amplifier control is available through the use of a control circuit or by direct bias injection. It is fabricated using a low phase noise HBT process which features full passivation for enhanced reliability.

Typical MAAL-011151-DIE Performance:

The MAAL-011151 ultra low phase noise amplifiers are sampling to customers in bare-die and packaged formats. As a bare die it measures 2.8 x 1.73 x 0.1 mm and it measures 5 x 5 mm in a 32-lead AQFN package.
