CO M UM4300 / UM7300 UM4300 / UM7300 UM4300 / UM7300 SWITCHING / ATTENUATOR PIN DIODES DESCRIPTION KEY FEATURES The UM4300 and UM7300 series combine a diode chip of extremely thick intrinsic Extremely low distortion performance region with a low thermal resistance construction. This results in diodes uniquely Useful frequency range extends below applicable to very low distortion linear attenuators and specialized functions. The 500 kHz UM4300 series, with large cross-sectional chip area offers the highest power Power dissipation to 20 W (UM4300) 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 Capacitance as low as 0.7 pF beyond 1 GHz. Low distortion is a result of transit time frequencies below 5 MHz. (UM7300) Operated as RF switches, either diode series can be operated at low dc reverse Voltage ratings to 1000V bias voltages, to hold off much higher RF voltage levels.
