1.16 to 1.26 and 1.56 to 1.61 GHz low noise amplifier with 27.5dB gain
350AMS_LNA_04 is a common receiver front-end device which is used to provide impedance matching to off-chip circuits and to perform first step low noise amplification to overcome noise of subsequent receiver stages.
This IP is two-stage LNA matched to 50Ohms at input and output both. The first stage is based on common-emitter amplifier with cascode and LC-resonant load with 1235MHz or 1590MHz center frequency modes, which are selected by logic level at SB input. To make input matching, external L-type matching network required. The second cascade is emitter follower which increases power gain and provides wideband output matching without any external components.
