Surface Acoustic Wave (SAW) and Bulk Acoustic Wave (BAW) duplexers of assessed quality - Part 2: Guidelines for the use
IEC 62604-2:2011 concerns the duplexers, which can separate receiving signal from transmitting signal and are key components for two-way radio communications. They are generally used in mobile phones using CDMA systems such as N-CDMA, W-CDMA / Universal Mobile Telecommunication System (UMTS). So far, dielectric duplexers have been mainly used. However, recently SAW duplexers, which are utilized surface acoustic wave (SAW), are becoming popular and replacing the dielectric duplexers year by year in recent mobile phones, because of their advantage of small size, light weight and good electrical performances. In addition to SAW duplexers, BAW duplexers, which are utilized bulk acoustic wave (BAW), are also becoming in the spotlight and popular because of their higher Q property and better performances especially in PCS band. It is neither the aim of these guidelines to explain theory, nor to attempt to cover all the eventualities which may arise in practical circumstances. These guidelines draw attention to some of the more fundamental questions, which should be considered by the user before he places an order for SAW and BAW duplexers for a new application. Such a procedure will be the user's insurance against unsatisfactory performance. Because SAW and BAW duplexers have very similar performance for the usage, it is useful and convenient for users that both duplexers are described in one standard.
Oberflächenwellen-(OFW-) und Volumenwellen-(BAW-)Duplexer mit bewerteter Qualität – Teil 2: Leitfaden für die Anwendung
Duplexeurs à ondes acoustiques de surface (OAS) et à ondes acoustiques de volume (OAV) sous assurance de la qualité - Partie 2: Lignes directrices d'utilisation
La CEI 62604-2:2011 concerne les duplexeurs qui peuvent séparer les signaux en réception des signaux en émission et qui sont des composants essentiels pour les radiocommunications bilatérales. Ils sont généralement utilisés dans les téléphones mobiles qui utilisent les systèmes CDMA comme les systèmes N-CDMA, W-CDMA / Universal Mobile Telecommunication System (UMTS). Jusqu'à présent, les duplexeurs diélectriques étaient majoritairement utilisés. Toutefois, au cours de la période récente, les duplexeurs OAS qui utilisent des ondes acoustiques de surface (OAS) se répandent et au fil des années ils remplacent les duplexeurs diélectriques dans les téléphones mobiles récents car ils présentent les avantages suivants: petites dimensions, faible poids et bonnes performances électriques. A côté des duplexeurs OAS, les duplexeurs OAV qui utilisent les ondes acoustiques de volume (OAV) sont de plus en plus connus et appréciés en raison de leur propriété Q plus élevée et de leurs meilleures performances en particulier dans la bande PCS. Les présentes lignes directrices ne sont pas destinées à expliquer la théorie de ces duplexeurs ni à couvrir toutes les situations qui peuvent apparaître dans la pratique. Elles attirent l'attention sur certains des aspects les plus importants qu'il convient qu'un utilisateur prenne en compte avant de passer commande pour des duplexeurs OAS et OAV pour une nouvelle application. Ainsi, l'utilisateur évitera d'être confronté à des performances non satisfaisantes. Dans la mesure où les duplexeurs OAS et les duplexeurs OAV présentent des performances très similaires dans leur utilisation, il est utile et pratique pour les utilisateurs que les deux types soient décrits dans une seule norme.
Radiofrekvenčni dupleksorji (SAW) in visokofrekvenčni dupleksorji (BAW) - 2. del: Navodilo za uporabo
Ta del standarda IEC 62604 zadeva dupleksorje, ki lahko ločijo sprejeti signal od oddanega signala in so ključni sestavni deli za dvosmerno radijsko komunikacijo. Na splošno se uporabljajo v mobilnih telefonih s sistemi CDMA, kot so N-CDMA, W-CDMA/univerzalni telekomunikacijski mobilni sistem (UMTS). Do sedaj so se v glavnem uporabljali dielektrični dupleksorji. Vendar v zadnjem času vse popularnejši postajajo radiofrekvenčni dupleksorji (SAW), ki zaradi svoje majhnosti, lahkosti in dobrih električnih zmogljivosti zamenjujejo dielektrične dupleksorje v novejših mobilnih telefonih. Poleg radiofrekvenčnih dupleksorjev so vse bolj priljubljeni visokofrekvenčni dupleksorji (BAW) zaradi svojih višjih lastnosti Q in boljših zmogljivosti, zlasti v pasu PCS. Cilj teh smernic ni pojasniti teorijo, niti poskusiti zajeti vse morebitne primere, do katerih lahko pride v praktičnih okoliščinah. Te smernice pozornost usmerjajo v nekatera bolj temeljna vprašanja, o katerih bi moral razmisliti uporabnik, preden se odloči za radiofrekvenčne ali visokofrekvenčne dupleksorje za novo aplikacijo. S tem se bo zavaroval pred nezadovoljivimi zmogljivostmi. Ker imajo radiofrekvenčni in visokofrekvenčni dupleksorji zelo podobne zmogljivosti za uporabo, je koristno in priročno za uporabnike, da sta oba dupleksorja opisana v enem standardu. Standardne specifikacije, kot so specifikacije IEC, katerih del so tudi te smernice, in nacionalne specifikacije ali podrobne specifikacije, ki so jih izdali proizvajalci, opredeljujejo razpoložljive kombinacije srednje frekvence, pasovne širine za prepuščanje in vklopne izgube za vsak oddajni in sprejemni filter ter raven izolacije med oddajnimi in sprejemnimi vrati itd. Te specifikacije so sestavljene tako, da vključujejo širok obseg radiofrekvenčnih in visokofrekvenčnih dupleksorjev s standardiziranimi zmogljivostmi. Zelo pomembno je, da uporabnik, kadar je le mogoče, svoje dupleksorje izbere med temi specifikacijami, če so na voljo, čeprav bo zato moral nekoliko spremeniti tokokrog, da bo omogočil uporabo standardnih dupleksorjev. To zlasti velja za izbiro običajne frekvence.
