UM4300 - SWITCHING / ATTENUATOR PIN DIODES

Download the UM4300 datasheet PDF. This datasheet also covers the UM4301 variant, as both devices belong to the same switching / attenuator pin diodes family and are provided as variant models within a single manufacturer datasheet.

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.

WWW.Microsemi .COM 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.
