WJ adds to InGaP/GaAs HBT gain block amplifier series

WJ Communications Inc of San Jose, CA, USA, a designer and supplier of RF products, has introduced the WJA1001 to its series of +5V active bias general purpose gain block amplifiers.

The WJA1001 is a broadband amplifier, based on advanced InGaP/GaAs HBT technology. It has been optimized internally to offer high linearity performance at 1 GHz, says the company. The MMIC amplifier is internally matched to 50 ohm, and only requires DC-blocking capacitors and a bias inductor for operation. It 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 100mA of current, with operation directly from a +5V supply voltage.

The WJA1001 is designed as a Darlington-pair amplifier configuration and is for general-purpose pre-driver applications within the 50 to 3000 MHz frequency range. Available in a surface-mount lead-free / green / RoHS-compliant SOT-89 package, the amplifier is suitable for current and next generation wireless applications, such as GSM, PCS, CDMA, W-CDMA, WiBro and WiMAX, repeaters, BTS transceivers, and RFID.

"Over the past year, the WJA series has given our customers a wide variety of high-performance and low-cost RF and IF amplifiers empowering engineers to meet and exceed product specifications as never before. The WJA1001 is another step in this direction," said Rufino Olay, director of worldwide marketing at WJ Communications.
