MRF21085

The MRF21085 is designed as RF power field effect transistors of N-channel enhancement-mode lateral MOSFETs for W-CDMA base station applications with frequencies from 2110 to 2170 MHz. Suitable for TDMA, CDMA and multicarrier amplifier applications. To be used in Class AB for PCN - PCS/cellular radio and WLL applications.

MRF21085 has ten features. (1) Typical 2-carrier W-CDMA performance for Vdd=28Volts, IDQ= 1000mA, f1=2135MHz, f2=2145MHz, channel bandwidth=3.84MHz, adjacent channels measured over 3.84MHz bandwidth at f1-5MHz and f2+5MHz, distortion products measured over a 3.84MHz bandwidth at f1-10MHz and f2+10MHz, each carrier peak/avg. =8.3dB at 0.01% probability on CCDF. (2) Internally matched, controlled Q, for ease of use. (3) High gain, high efficiency and high linearity. (4) Integrated ESD protection. (5) Designed for maximum gain and insertion phase flatness. (6) Capable of handling 5:1 VSWR, at 28Vdc, 2170MHz, 90Watts CW output power. (7) Excellent thermal stability. (8) Characterized with series equivalent large signal impedance parameters. (9) Available with low gold plating thickness on leads. L suffix indicates 40'' nominal. (10) In tape and reel. R3 suffix = 250 units per 56 mm, 13 inch reel. That are all the main features.
