MRF247MOTOROLA RF DEVICE DATA The RF Line /C0078/C0080/C0078 /C0083/C0105/C0108/C0105/C0099/C0111/C0110 /C0082/C0070 /C0080/C0111/C0119/C0101/C0114 /C0084/C0114/C0097/C0110/C0115/C0105/C0115/C0116/C0111/C0114 The MRF247 is designed for 12.5 Volt VHF large–signal amplifier applications in industrial and commercial FM equipment operating to 175 MHz.

  • Specified 12.5 Volt, 175 MHz Characteristics — Output Power = 75 Watts Power Gain = 7.0 dB Min Efficiency = 55% Min
  • Characterized With Series Equivalent Large–Signal Impedance Parameters
  • Internal Matching Network Optimized for Minimum Gain Frequency Slope Response Over the Range 136 to 175 MHz
  • Load Mismatch Capability at Rated Pout and Supply Voltage MAXIMUM RATINGS Rating Symbol Value Unit Collector–Emitter Voltage VCEO 18 Vdc Collector–Base Voltage VCBO 36 Vdc Emitter–Base Voltage VEBO 4.0 Vdc Collector Current — Peak IC 20 Adc Total Device Dissipation @ TC = 25°C (1) Derate above 25°C PD 250 1.43 Watts W/°C Storage Temperature Range Tstg –65 to +150 °C THERMAL CHARACTERISTICS Characteristic Symbol Max Unit Thermal Resistance, Junction to Case (2) R θJC 0.7 °C/W ELECTRICAL CHARACTERISTICS (TC = 25°C unless otherwise noted.) Characteristic Symbol Min Typ Max Unit OFF CHARACTERISTICS Collector–Emitter Breakdown Voltage (IC = 100 mAdc, IB = 0) V(BR)CEO 18 — — Vdc Collector–Emitter Breakdown Voltage (IC = 50 mAdc, VBE = 0) V(BR)CES 36 — — Vdc Emitter–Base Breakdown Voltage (IE = 10 mAdc, IC = 0) V(BR)EBO 4.0 — — Vdc (1) This device is designed for RF operation. The total device dissipation rating applies only when the device is operated as an RF amplifier. (2) Thermal Resistance is determined under specified RF operating conditions by infrared measurement techniques.
