GC4210

TOC Control Devices HIGH SPEED PIN DIODES DESCRIPTION The GC4200 series are high speed (cathode base) PIN diodes made with high resistivity epitaxial silicon material. These diodes are passivated with silicon dioxide for high stability and reliability and have been proven by thousands of device hours in high reliability systems. These devices 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 GC4200 series will operate with as little as +10 mA forward bias. APPLICATIONS The GC4200 series can be used in 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 switches, channel or antenna selection switches (telecommunications), duplexers (radar) and digital phase shifters (phased arrays). The GC4200 series are also used as passive and active limiters for low to moderate RF power levels. Attenuator type applications include amplitude modulators, AGC attenuators, power levelers and level set attenua- ELECTRICAL SPECIFICATIONS: TA = 25°C MODEL NUMBER BREAKDOWN VOLTAGE (IR = 10µA MAX) VB (MIN) (Volts) JUNCTION CAPACITANCE CJ-10 (MAX) (pF) 1 SERIES RESISTANCE (20mA, 1 GHz) RS20 (MAX) (Ohms) 2 CARRIER LIFETIME (I4=6mA, IF=10mA) TL (TYP) (nS) THERMAL RESISTANCE (MAX) (°C/W) GC4270 GC4271 GC4272 GC4273 GC4274 GC4275 GC4210 GC4211 GC4212 GC4213 GC4214 GC4215 GC4220 GC4221 GC4222 GC4223 GC4224 GC4225 70 70 70 70 70 70 100 100 100 100 100 100 250 250 250 250 250 250 0.06 0.10 0.20 0.30 0.40 0.50 0.06 0.10 0.20 0.30 0.40 0.50 0.06 0.10 0.20 0.30 0.40 0.50 1.5 1.0 0.8 0.7 0.6 0.5 1.5 1.0 0.75 0.6 0.5 0.35 2.5 2.0 1.5 1.0 0.8 0.6 60 60 60 60 60 60 100 100 100 100 100 100 400 400 400 400 400 400 80 70 70 60 50 40 80 70 70 60 50 40 80 70 70 60 50 40 Notes: 1. Capacitance is measured at 1 MHz and -10 volts. 2. Resistance is measured using transmission loss techniques. 3. This series of devices is available in standard case styles 00, 15, 30, 35 and 85, plus other styles on request. The tabulated specifications above are for the style 30 package. Diodes may also be available in other case styles. Each type offers trade offs in series resistance, junction capacitance and carrier lifetime; the proper choice of which depends on the end application. Reverse polarity diodes (NIP) and higher voltage PIN and NIP diodes are also available. (See data sheets for GC4300, GC4400, and GC4500 series respectively.)
