Remote Sensor Location Schemes

Some applications require that sensing be performed in a location that precludes the presence of RF electronic circuitry. For example, the location may be subjected to extreme temperatures or pressures, or it may simply not be large enough to allow room for the circuitry. In all of these situations, mounting of the sensor remote from the RF electronics is necessary. 

For two-port devices (e.g., SAW delay lines), separation of the sensor from the electronics can be accomplished by simply connecting a transmission line —
