Vcontrol voltage can be applied to the base of an NPN transistor with the collector connected to the +5V and a 240 ohm
current limiting resistor to drive the VG024 as a VGA. This data is represented at 240 MHz in the above graph. Normalized
performance can be obtained for the RF circuit tuned from 70-1000 MHz using the temperature compensation application
circuit for 240 MHz shown on the previous page. Reducing Roffset increases the overall insertion loss and allows more
change (reduction in the value) in Rslope to compensate for more amplifiers or larger temperature changes.
