FEATURES
DESCRIPTION
The U443 Series is an N-Channel Monolithic Dual JFET
designed for high speed amplifier circuits. Featuring high gain
( > 6 mS typical), low leakage (< 1pA typical) and low noise
this device is an excellent choice for high performance test
and measurement, wideband amplifiers and VHF/UHF
circuits.
