+5V Active Bias General Purpose Gain Block Amplifiers
The WJA1xxx Series are high-performance broadband amplifiers that offer high linearity, housed in a low-cost surface-mount package. An internal active bias circuitry is designed to enable stable performance over temperature. These devices are Darlington pair amplifiers operating directly off a voltage supply where a dropping resistor is not needed. The WJA1xxx amplifiers use a high-reliability InGaP/ GaAs HBT process technology and are internally matched to 50 Ohm. These products are available in small form factor, lead-free/RoHS-compliant SOT-89 package.
