| polyfet rf devices General Description Silicon VDMOS and LDMOS transistors designed specifically for broadband RF applications. Suitable for Military Radios, Cellular and Paging Amplifier Base Stations, Broadcast FM/AM, MRI, Laser Driver and others. TM "Polyfet" process features gold metal for greatly extended lifetime. Low output capacitance and high Ft enhance broadband performance Total Device Dissipation 350 Watts Junction to Case Thermal Resistance 0.5 o C/W Maximum Junction Temperature 200 o C Storage Temperature F1074 PATENTED GOLD METALIZED SILICON GATE ENHANCEMENT MODE RF POWER VDMOS TRANSISTOR 100 Watts Gemini Package Style AR HIGH EFFICIENCY, LINEAR, HIGH GAIN, LOW NOISE o ABSOLUTE MAXIMUM RATINGS (TC = 25 C) DC Drain Current Drain to Gate Voltage 70 V Drain to Source Voltage 70 V Gate to Source Voltage 30V -65 o C to 150o C 16 A RF CHARACTERISTICS ( 100 WATTS OUTPUT ) SYMBOL Gps PARAMETER Common Source Power Gai Drain Efficienc Load Mismatch Toleranc MIN 12 60 20:1 TYP MAX UNITS dB % Relative TEST CONDITIONS Idq = 1.6 A, Vds = 28.0 V, F = 400 MHz Idq = 1.6 A, Vds = 28.0 V, F = 400 MHz Idq = 1.6 A, Vds = 28.0 V, F = 400 MHz VSWR ELECTRICAL CHARACTERISTICS (EACH SIDE) SYMBOL Bvdss Idss Igss Vgs gM Rdson Idsat Ciss Crss Coss PARAMETER Drain Breakdown Voltag Zero Bias Drain Curren Gate Leakage Curren Gate Bias for Drain Curren Forward Transconductanc Saturation Resistanc Saturation Curren Common Source Input Capacitanc Common Source Feedback Capacitanc Common Source Output Capacitanc 1 3.2 0.35 22 132 16 80 MIN 65 4 1 7 TYP MAX UNITS V mA uA V Mho Ohm Amp pF pF pF TEST CONDITIONS Ids = 0.2 A, Vgs = 0V Vgs = 0V Vgs = 30V Vgs = Vds Vds = 28.0 V, Vds = 0 V, Ids = 0.4 A, Vds = 10V, Vgs = 5V Vgs = 20V, Ids = 16 A Vgs = 20V, Vds = 10V Vds = 28.0 V, Vgs = 0V, F = 1 MHz Vds = 28.0 V, Vgs = 0V, F = 1 MHz Vds = 28.0 V, Vgs = 0V, F = 1 MHz POLYFET RF DEVICES REVISION 1/12/98 1110 Avenida Acaso, Camarillo, CA 93012 TEL:(805) 484-4210 FAX:(805) 484-3393 EMAIL:Sales@polyfet.com URL:www.polyfet.com F1074 POUT VS PIN GRAPH F1074 POUT VS PIN 400 MHZ; IDQ=1.6A; VDS=28.0V F1B 4DIE CAPACITANCE CAPACITANCE VS VOLTAGE 160 140 120 100 13.50 13.00 12.50 12.00 1000 Coss 100 Ciss 11.50 80 Efficiency = 65% 60 40 0 2 4 6 8 10 12 POUT 11.00 Crss 10.50 10.00 14 GAIN 10 0 5 10 15 VDS IN VOLTS 20 25 30 PIN IN WATTS IV CURVE F1B 4DIE IV CURVE 30 ID AND GM VS VGS F1B 4 DIE GM & ID vs VGS 100 25 Id 20 10 15 10 1 5 Gm 0 0 2 4 6 8 10 Vds in Volts 12 14 16 18 20 0.1 0 2 4 6 Vgs in Volts 8 10 12 14 Vg = 2V Vg = 4V Vg = 6V Vg = 8V Vg = 10V Vg = 12V S11 AND S22 SMITH CHART PACKAGE DIMENSIONS IN INCHES POLYFET RF DEVICES REVISION 1/12/98 1110 Avenida Acaso, Camarillo, CA 93012 TEL:(805) 484-4210 FAX:(805) 484-3393 EMAIL:Sales@polyfet.com URL:www.polyfet.com |
