We see from your search that you're looking for information on the term "SPDT",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Mixer claims top performance from 815 to 1000MHz from
Maxim Integrated Products, which we summarised at the time by saying "Delivers an unparalleled combination of linearity, noise performance, and component integration for 2.5G/3G wireless-infrastructure applications".
Earlier in the week,
we featured the news release Switches enable high-speed ATE systems from
Agilent Technologies Europe: "Coaxial solid-state PIN diode switches target engineers designing manufacturing test systems or requiring a fast switching solution to validate component performance".
In January 2008, we covered the news from Vishay Siliconix
concerning its DG469 and DG470
- take a look at Little resistance to analogue switch upgrades
which says: "The DG469 and DG470 offer a very low 3.6ohm typical and 4.2ohm maximum on-resistance with typical flatness of 0.4ohm".
Take a look also at the news release from Innovative Micro Technology (IMT), Process makes RF relays more economical,
as well as Analogue switches suit audio, video and data from Vishay Siliconix,
and Attenuator/switch drivers ease validation from Agilent Technologies Europe.
