Titolo: | NONLINEARITY INVESTIGATION AT 44 GHz USING PROTOTYPE UNITS: BEM44_B3_DC AND BEM44_B4_DC | Autori: | CUTTAIA, FRANCESCO | Data pubblicazione: | 2006 | Numero: | PL-LFI-PST-RP-073 | Abstract: | Several tests have been performed at JBO to investigate the problem of representative FM BEM compression. Evidence of some compression happening inside the BEM is given by the high noise temperatures measured during the December test campaign, firstly on FEM 4F2 and then on FEM 4F3 when coupled to representative BEMs. JBO has four representative BEMs, two (B3 and B4) provided with diodes and then having a DC output, two (B1 and B2) without any diode and having an RF output. During last 2005 JBO tests, DC BEMs have shown to be compressed while RF BEMs have shown only a weak compression. Dedicated tests have been performed during the last test campaign to investigate the degree of compression, common features between the two BEMs, the noise temperature reachable in compressed conditions. Comparison tests have been also performed to check the repeatability of procedures used. | URI: | http://hdl.handle.net/20.500.12386/33460 | Fulltext: | open |
