MGA-635P8 GaAs ePHEMT MMIC 3.5 GHz Low Noise Amplifier with Superior Noise and Linearity Performance

چکیده
Depending on whether frequency domain duplexing or time domain duplexing (TDD) is used, one antenna can be shared by both transmitter and receiver via a frequencyselective diplexer or an RF switch. Additionally, a band-pass filter may be inserted before the LNA to prevent blocking or desensitization by a strong out-of-band interferer. However, both the duplexer and the filter have losses. As these losses occur before the LNA, they have a deleterious effect on receiver sensitivity [2]. Therefore, an LNA with better noise performance can relax the loss requirements for the duplexer and filter.

Cellular base stations (BTS) and microwave relays have detached LNA stages located up in the aerial tower in order to mitigate NF degradation from pre-LNA cable loss. In the BTS architecture, the LNA stage is preceded by a transmit-receive (Tx-Rx) diplexer for duplexing a common aerial and by an interference fi lter for preventing out-ofband blocking or desensitization. However, both duplexer a...

متن کاملA New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
