RF3827
Theory of Operation
RF3827 can be used as both low noise amplifier and linear transmit driver. Internal matching is such that the part can be used
effectively in both 50 and 75 systems. The standard evaluation board is 50, as are the corresponding specifications
shown within the data sheet. Perhaps more convenient for the 75 designer, would be alternate products RF2360 and CXE2089Z. These two devices see very similar performance to RF3827, and standard 75 evaluation boards are available.
An important note concerning RF3827 layout would apply to package pins 2 and 10. These two pins have no internal connection. They are, however, connected externally to RF input and output traces on the standard evaluation board. Given their close
proximity to the actual input and output pins, this is simply a matter of convenience.
The standard RF3827 evaluation board is matched to provide excellent performance from 50MHz to 1000MHz. An application
schematic is also shown for 5MHz to 200MHz, in the event lower frequency operation is desired. Specifications are shown in
the tabular sections for the condition VDD =8V. Note that graphs are also provided herein for the common design case where
VDD =5V.
