Rochester Electronics TRANSISTORS - Transistors - FETs, MOSFETs - RF - MRF21085R3 MRF21085R3

The MRF21085R3 is an N-channel enhancement-mode lateral MOSFET for W-CDMA base stations from 2110 to 2170 MHz, used in CDMA, TDMA, and multicarrier Class AB amplifiers. It is packaged in a CASE 465-06, NI-780 case measuring 33.91 to 34.16 mm in length, 9.65 to 9.91 mm in width, and 1.45 to 1.70 mm in height. Rated for 65 V drain-source voltage and 224 W power dissipation at 25°C, it has a junction-to-case thermal resistance of 0.78 °C/W. Under 2-carrier W-CDMA conditions at 28 Vdc, it provides 19 W average output power with 13.6 dB gain and 23% efficiency, and reliably handles a 5:1 VSWR at 90 W CW output. Integrated ESD protection meets Human Body Model Class 1 and Machine Model M3 standards.
