Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: help: transceiver switch

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.
