UM4300 / UM7300
FOR ATTENUATOR APPLICATIONS
DESCRIPTION
The UM4300 and UM7300 series combine
a diode chip of extremely thick intrinsic
region with a low thermal resistance
construction. This results in diodes uniquely
applicable to very low distortion linear
attenuators and specialized functions. The
UM4300 series, with large cross-sectional
chip area offers the highest power
capability, of the two series. The UM7300
series offers lower capacitance.
Both diode series are intended for use in linear
attenuators operating from HF to beyond 1 GHz.
Low distortion is a result of transit time
frequencies below 5 MHz.
Operated as RF switches, either diode series can
be operated at low dc reverse bias voltages, to
hold off much higher RF voltage levels.
