WJ Communications - WJA1021

The WJA1021 is a cascadable Gain Block that offers high linearity in a low-cost surface-mount package. At 1.9 GHz, the WJA1021 typically provides 17.5 dB gain, +37.5 dBm OIP3, and +19 dBm P1dB. The device is housed in a lead- free/green/RoHS-compliant industry-standard SOT-89 SMT package using a NiPdAu plating to eliminate the possibility of tin whiskering. The WJA1021 consists of Darlington pair Amplifier using a high reliability InGaP/GaAs HBT process technology. The Amplifier has been optimized internally to offer very high linearity performance at 1.9 GHz while drawing very low current. The MMIC Amplifier is internally matched to 50 and only requires DC-blocking capacitors and a bias , inductor for operation. An internal active bias is designed to enable stable performance over temperature and allow for operation directly from a +5V supply voltage. By WJ Communications, Inc.
