hi,

from these websites i am finding only SPDT, SP4T..... type switches.

they have not mentioned any switching period.

how can we identify it as TDD switch? Is it SPTT switch?


thank you
Chan re gowda

In TDD both the uplink (UL) and downlink (DL) traffic use the same frequency, but at different times. So, a simple SPDT can do the job.

The Guard Time between TX and RX and vice-versa is depending by the system used, but generally this is not shorter than few microseconds, which isn’t a big issue for most of the RF switches from the sites above.

Selecting an RF switch have to look also for: power handling, isolation, insertion loss, linearity, etc.
