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
