| e PTB 20074 14 watts, 1.477-1.501 GHz Cellular Radio RF Power Transistor Description The 20074 is a class AB, NPN, common emitter RF power transistor intended for 26 Vdc operation from 1.477 to 1.501 GHz. Rated at 14 watts minimum output power, it may be used for both CW and PEP applications. Ion implantation, nitride surface passivation and gold metallization are used to ensure excellent device reliability. 100% lot traceability is standard. 14 watts, 1.477-1.501 GHz Class AB Characteristics 30% Collector Efficiency at 10 watts Gold Metallization Silicon Nitride Passivated Typical Output Power vs. Input Power 20 Output Power (Watts) 15 200 74 LOT COD E 10 VCC = 26 V 5 ICQ = 50 mA f = 1.501 GHz 0 0 1 2 3 4 Input Power (Watts) Package 20201 Maximum Ratings Parameter Collector-Emitter Voltage Collector-Base Voltage Emitter-Base Voltage (collector open) Collector Current (continuous) Total Device Dissipation at Tflange = 25C Above 25C derate by Storage Temperature Range Thermal Resistance (Tflange = 70C) TSTG RJC Symbol VCER VCBO VEBO IC PD Value 50 50 4.0 1.4 25 0.14 -40 to +150 7.0 Unit Vdc Vdc Vdc Adc Watts W/C C C/W 1 9/28/98 PTB 20074 Electrical Characteristics Characteristic Breakdown Voltage C to E Breakdown Voltage C to E Breakdown Voltage E to B DC Current Gain (100% Tested) e Conditions IB = 0 A, IC = 40 mA, RBE = 22 VBE = 0 V, IC = 40 mA IC = 0 A, IE = 20 mA VCE = 10 V, IC = 0.25 A Symbol V(BR)CER V(BR)CES V(BR)EBO hFE Min 50 50 4 20 Typ -- -- 5 50 Max -- -- -- 120 Units Volts Volts Volts -- RF Specifications (100% Tested) Characteristic Gain (VCC = 26 Vdc, Pout = 10 W, ICQ = 50 mA, f = 1.501 GHz) Power Output at 1 dB Compression (VCC = 26 Vdc, ICQ = 50 mA, f = 1.501 GHz) Collector Efficiency (VCC = 26 Vdc, Pout = 10 W, ICQ = 50 mA, f = 1.501 GHz) Intermodulation Distortion (VCC = 26 Vdc, Pout = 10 W(PEP), ICQ = 50 mA, f1 = 1.500 GHz, f2 = 1.501 GHz) Load Mismatch Tolerance (VCC = 26 Vdc, Pout = 10 W, ICQ = 50 mA, f = 1.501 GHz--all phase angles at frequency of test) -- -- 5:1 -- Symbol Gpe P-1dB C IMD Min 7 13 30 -- Typ 8 15 -- -30 Max -- -- -- -- Units dB Watts % dBc Ericsson Components RF Power Products 675 Jarvis Drive Morgan Hill, CA 95037 USA Telephone: 408-778-9434 1-877-GOLDMOS (1-877-465-3667) e-mail: rfpower@ericsson.com www.ericsson.com/rfpower Specifications subject to change without notice.
