3.5GHz Dual-channel switch + LNA lowers noise
Stephen LawElectronics dual channel LNA module switch
PSEMI Two multi-chip modules featuring dual-channel switches, the PE53230 for 3.3–3.8 GHz and the PE53231 for 3.5–4.0 GHz. Device contain two switches and two LNAs for high and low band frequencies. Module portfolio delivers the low noise, at less than 1dB, enabling best-in-class receiver sensitivity and performance while handling 20W average input power enabling removal of external circuitry. Built for applications across wireless infrastructure including TDD-LTE macro and micro cells, 5G massive MIMO systems and TDD-based communication systems, products feature high gain and gain flatness. They can function as a failsafe with unexpected high-power signals coming in from Tx, while improving receiver channel sensitivity with low noise figures. Combining high linearity (IIP3) with low power consumption, the new modules are highly integrated solutions that do not require any external matching networks.
