Switch+ LNA Modules for 5G Massive MIMO Base Stations


pSemi's family of switch + low-noise amplifier (LNA) modules for 5G massive MIMO base stations are now available in volume production.

With an ultra-low noise figure and excellent input power handling, the PE53111, PE53211, PE53110 and PE53210 are ideal for protecting remote radio units that operate in the sub-6 GHz frequency bands. The PE53111 and the PE53211 cover a frequency range from 2.3 to 2.7 GHz (bands 40, 41, n7, n38, n41), while the PE53110 and PE53210 extend from 3.3 to 3.8 GHz (bands 42, 43, 48, 49, n78). In a single-channel or dual-channel configuration, the receiver modules integrate LNAs with bypass function and high-power switches. The switch + LNA modules offer ESD protection up to 1kV HBM and operate in environments up to 105 degrees Celsius. The modules have a compact package size of 32-lead, 5 x 5 mm LGA.
