hello there! i have a big problem
in what switch or switching technique to be used regarding our Radio
Frequency Identification (RFID)Reader/interrogator which is a transceiver.
we wanted to increase the read range or the effective area where
our RFID can read the RFID tag...so we design and build an amplifier
for transmit and receive operation (though we still don't know if it
will work when integrated with the circuit). Modulation used for communication
from reader to tag is amplitude shift keyingn and loading modulation
from tag to reader.
It happens that our RFID reader/interrogator
have only one node for transmitting and receiving signals/data. is there
any way to synchronize the switching of the transmit and receive amplifier?
is there a device that can disable and isolate the receive amplifier
during transmit mode and vice versa.
please help me...thank you
very much!

It sounds like you need a diversity switch. Hittite
Microwave Corporation have several. I would try and call them.

use MACOM, Skyworks RF Switches or
use discrete PIN Diodes for Switching.
