Tyco Electronics has developed a new family of ultra low noise amplifiers (LNA) with less than 1 dB noise figure (NF) across the designed frequency range that are appropriate for a variety of applications including global positioning systems (GPS), WiMAX, digital audio broadcasting (DAB) and multimedia over coax alliance (MoCA) specifications.
Each LNA is tuneable over a wide frequency range and requires minimum off-chip matching components, which allows for tuning optimal noise figure and gain over a wide frequency range.
The M/A-COM MAAL-007304 and MAAL-007306 are high gain amplifiers in a RoHS-compliant SOT-26 surface mount plastic package. They employ a monolithic two-stage self-biased design and typically operate from a single 3,0 V supply. The 007304 is designed to achieve noise of 0,7 dB, current consumption of 11,5 mA and gain of 25,5 dB up to 3,0 GHz, while the 007306 has a higher operating current and OIP3 in order to support higher linearity requirements for the infrastructure market up to 2,0 GHz.
The MAAL-008550 low noise amplifier is packaged in a RoHS SC-70 compliant surface mount plastic package, employing a single-stage self-biased design and typically runs from a single 3,0 V supply. It features a noise figure of 0,75 dB while only consuming 7,5 mA of current and 12,5 dB of gain at 2,3 GHz.
