Blocking capacitors are required on all RF ports (39 pF used intermodulation products are required. Typical for data measurements). applications include radio, cellular, wireless LANs, 3. Vs = +5 0.2 VDC must be applied at RF1 or RF2 using a GPS equipment and other gain/level control circuits. 10 k or greater pull-up resistor. The MAATSS0016 is fabricated using a mature 1 micron GaAs MESFET process. The process features full chip passivation for increased Pin Configuration performance and reliability.
