Model VBM2500-3 is a solid-state amplifier capable of
generating 3W minimum power over the 10-2500MHz
frequency range. The amplifier is designed to operate
from a 12V DC supply, and so is applicable for either
equipment bus or battery operation.
Cooling is by means of a removable heatsink, sufficient
for convection cooling in most environments. Only
minimal supplementary forced air cooling is required for
operation at the maximum operating temperature.
Protection against excess temperature is by means of an
internal sensor.
The amplifier is designed for rugged operation into any
passive load at maximum power, and is unconditionally
stable. For use in low level signal applications, the
amplifier features low noise figure. The use of an HBT
input stage gives a 1/f corner frequency below the low
frequency limit of the amplifier, and so the amplifier will
not exhibit the poor low frequency noise performance of
FET amplifiers.
Intended applications for the amplifier are: high output
buffer for rf sweepers; EMC systems; ECM requirements;
high speed, long distance digital/analogue links and
general laboratory use.
