The MGA-633P8, MGA-634P8, and MGA-635P8 low-noise amplifiers (LNAs) from Avago Technologies enhance RF performance while enabling space and cost savings for both new and redesigned wireless infrastructure basestations, according to the company. They also offer ultra-low noise figures of 0.37, 0.44, and 0.56 dB, respectively.

These LNAs come in a compact footprint with a low profile, measuring 2.0 by 2.0 by 0.75 mm3 in an eight-pin quad flat no-lead (QFN) package. They boast high gain ranging from 17.4 to 18 dB as well as high linearity—1-dB gain compression measurement (P1dB) of about 22 dBm with an output third-order intercept point (OIP3) greater than 35 dBm. 

Furthermore, the LNAs are based on gallium-arsenide (GaAs) enhancement-mode pseudomorphic high-electron mobility transistor (E-pHEMT) technology (0.25 µm) and comply with the European Union’s Restrictions on Hazardous Substances (RoHS).

The MGA-633P8 is designed for optimum use between 450 MHz and 2.0 GHz. The MGA-634P8 handles the 1.5- to 2.3-GHz frequency spectrum. And, the MGA-635P8 targets frequencies between 2.3 and 4.0 GHz. Wireless infrastructure applications include Long-Term Evolution (LTE), WiBro, UMTS, GSM, and CDMA.

The MGA-633P8, MGA-634P8, and MGA-635P8 LNAs from Avago Technologies enhance RF performance while enabling space and cost savings for both new and redesigned wireless infrastructure basestations.

The MGA-635P8 costs $2.31 each in 10,000-piece quantities.
