San Jose, Calif.—Designed to offer high linearity performance at the 1GHz cellular band frequency, WJ Communications Inc.'s cascadable +5V active bias gain-block amplifier is produced using InGaP/GaAs HBT process technology.
The WJA1001 is aimed at current and next-generation wireless applications such as GSM, PCS, CDMA, W-CDMA, WiBro and WiMAX, repeaters, BTS transceivers, and RFID.
The MMIC amplifier is internally matched to 50-ohm. The WJA1001 only requires DC-blocking capacitors and a bias inductor for operation. The amplifier features high-cascadable gain with 19 dB gain at 900 MHz, a +20 dBm 1-dB compression point and +45 dBm OIP3 at 900MHz while drawing only 100mA of current with operation directly from a +5V supply voltage.
