UM4300 / UM7300

SWITCHING / ATTENUATOR PIN DIODES

DESCRIPTION

KEY FEATURES

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.
