| e PTB 20188 4 Watts P-Sync, 470-860 MHz UHF TV Linear Power Transistor Description The 20188 is an NPN common emitter UHF power transistor intended for 25 Vdc class A operation from 470 to 860 MHz. It is rated at 4 watts output power, and 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. 4 Watts (P-sync), 470-860 MHz Class A Characteristics Gold Metallization Silicon Nitride Passivated Typical Output Power vs. Input Power 6 Output Power (Watts) 5 4 3 2 1 0.18 LOT 2018 COD 8 E VCC = 25 V IC = 850 mA f = 860 MHz 0.37 0.56 0.75 0.94 1.13 Input Power (Watts) Package 20206 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) Symbol VCER VCBO VEBO IC PD TSTG RJC Value 40 65 4.0 6.7 65 0.4 -40 to +150 4.5 Unit Vdc Vdc Vdc Adc Watts W/C C C/W 1 9/28/98 PTB 20188 Electrical Characteristics (100% Tested) Characteristic Breakdown Voltage C to E Breakdown Voltage C to E Breakdown Voltage E to B DC Current Gain e Conditions IB = 0 A, IC = 50 mA VBE = 0 V, IC = 50 mA IC = 0 A, IE = 5 mA VCE = 5 V, IC = 250 mA Symbol V(BR)CEO V(BR)CES V(BR)EBO hFE Min 25 55 3.5 20 Typ 30 70 5 50 Max -- -- -- 100 Units Volts Volts Volts -- RF Specifications Characteristic Gain (VCC = 25 Vdc, IC = 850 mA, Pout = 4 W(P-sync), f1 = 860 MHz, Vision = -8dB, f2 = 863.5 MHz, Subcarrier = -16dB, f3 = 864.5 MHz, Sound = -7dB) Intermodulation Distortion (VCC = 25 Vdc, IC = 850 mA, Pout = 4 W(P-sync), f1 = 860 MHz, Vision = -8dB, f2 = 863.5 MHz, Subcarrier = -16dB, f3 = 864.5 MHz, Sound = -7dB) Load Mismatch Tolerance (VCC = 25 Vdc, IC = 850 mA, Pout = 4 W(P-sync), f1 = 860 MHz, Vision = -8dB, f2 = 863.5 MHz, Subcarrier = -16dB, f3 = 864.5 MHz, Sound = -7dB--all phase angles at frequency of test) Symbol Gpe Min 7.0 Typ -- Max -- Units dB IMD -- -- -58 dBc -- -- 3:1 -- Impedance Data (data shown for fixed-tuned broadband circuit) (VCC = 25 Vdc, IC = 850 mA, Pout = 4 W(P-sync)) Z0 = 50 Z Source Z Load Frequency MHz 470 665 860 R 1.1 1.2 0.7 Z Source jX -1.7 -3.4 -4.7 R 12.2 8.3 4.3 Z Load jX +9.8 +8.8 +6.9 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.
