Linear Technology announces the LTC6433-15, a wideband 15dB gain block amplifier offering outstanding linearity of 47dBm OIP3 (output third order intercept) and 3.22dB noise figure at 150MHz. The amplifier has excellent OP1dB (output 1dB compression point) of 19.2dBm. The LTC6433-15 is uniquely different from other gain block amplifiers that are typically built using GaAs or pHEMT processes.

The LTM8003’s pinout is FMEA (failure mode effects analysis) compliant, so the output voltage stays at or below the regulation voltage in the event of short-circuit to GND, short-circuit to a neighbouring pin or if a pin is left floating.
