The issues causing current connector leakage have been identified and modified with manufactural treatments. The newly developed connectors can operate up to 18 GHz and beyond. Small RF connectors are perfect fit for pico/nano satellites and no additional shielding is needed to secure signal paths suffering intentional or unintentional radiation emissions.","PeriodicalId":193747,"journal":{"name":"2022 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"2008 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125623206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With high-fidelity, we emphasize that any change of parameters on the mission level, e.g., orbital parameters or the antennas used on satellite or ground station, is automatically reflected down to the radio frequency (RF) link model and finally evaluated on the digital symbol level, including end-to-end performance on the bit level. We evaluate this approach by simulating the link of the UWE-4 mission [1] and comparing the simulation results with raw-data recorded from the Telemetry, Tracking and Control (TT&C) link.","PeriodicalId":193747,"journal":{"name":"2022 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123242226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transmissions in these bands now utilize complex digital modulations to increase their bandwidth efficiency. HPAs made for these modulations must be linear in order to minimize distortion. To achieve the required linearity, amplifiers are operated at reduced power, which results in lower efficiency, larger and heavier HPAs, extra heat, and higher costs. Linearization is used to cancel distortion and allow HPAs to operate closer to their maximum power; especially at millimeter-wave (MMW) where power is costly. Linearizers typically cover a single frequency band. The linearizer discussed here operates at two critical MMW SATCOM bands. When operated with a suitable wideband HPA, it allows efficient linear operation over both bands and considerable savings over HPAs for the individual bands. It can be used with both TWTAs and SSPAs, but was developed for a TWTA application. It is believed to the first multi-band linearizer developed for MMW.","PeriodicalId":193747,"journal":{"name":"2022 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"8 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120986616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main payload is a miniaturized SDR (software defined radio) with 0.5 W Tx power and adaptive coding and modulation scheme. The orbit performance e.g. link budget, differential drag control and radiation tolerance are presented.
