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.  
Extremely low distortion performance  
Useful frequency range extends below  
500 kHz  
Power dissipation to 20 W (UM4300)  
Capacitance as low as 0.7 pF  
(UM7300)  
Voltage ratings to 1000V  
Non cavity design  
Thermally matched  
Isolated stud package available  
ABSOLUTE MAXIMUM RATINGS AT 25º C  
(UNLESS OTHERWISE SPECIFIED)
