UM4300 / UM7300
SWITCHING / ATTENUATOR PIN DIODES
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.
