+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 5V supply and no dropping resistor is 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.
