HIGH VOLTAGE PIN DIODES

Control Devices

DESCRIPTION

The GC4400 series are high voltage, high power (cath­ode base) PIN diodes. These high resistivity silicon de­vices are passivated with silicon dioxide for high stability
and reliability and have been proven by thousands of de­vice hours in high reliability systems.

Each device can withstand storage temperatures from

-65° to +200°C and will operate over the range from -55°
to +150°C. All devices meet or exceed military environ­mental specifications of MIL-S-19500.

The GC4400 series will operate typically with +50 mA
forward bias. Breakdown voltages are available up to
1000 volts.

APPLICATIONS

The GC4400 series can be usedin RF circuits as an on/off
element, as a switch, or as a current controlled resistor in
attenuators extending over the frequency range from
UHF through Ku band.

Switch applications include high speed switches (ECM
systems), TR or lobing switches, channel or antenna se­lection switches (telecommunications), duplexers (ra­dar) and digital phase shifters (phased arrays).

The GC4400 series can be usedin RF circuits as an on/off
at moderate RF power levels.

Attenuator type applications includeamplitudemodulators,
AGC attenuators, power levelers and level set attenuators.

ELECTRICAL SPECIFICATIONS: TA= 25°C
