WJ Communications Introduces New Family of High-Linearity and Low-Current Amplifiers for Broadband RF and IF Applications
High-Performance 5V InGaP/GaAs Amplifiers offer Reliable & Superior RF Solutions for Existing and Next Generation Wireless Technologies
SAN JOSE, Calif., May 10, 2007 -- WJ Communications, Inc. (NASDAQ:WJCI), a leading designer and supplier of radio frequency (RF) products and solutions for the wireless infrastructure and radio frequency identification (RFID) reader markets, today announced a new family of high-performance broadband amplifiers, the
WJA amplifier family. The WJA broadband amplifiers offer up to 20 dB of gain and an output IP3 up to 43 dBm while consuming only 60-90 mA from a +5V supply. Utilizing the high-reliability InGaP/GaAs HBT process technology, the WJA amplifiers exceed the increasingly complicated requirements of the next generation communication systems. Additionally the WJA amplifiers are ideal solutions for existing and next-generation cellular (CDMA, GSM/GPRS/EDGE, W-CDMA, and WiMAX) infrastructure, CATV and other wireless applications.
The first WJA amplifiers to be introduced are the RF (WJA10xx) and the IF (WJA15xx) amplifier series. These new products offer an excellent mix of power gain, linearity, and supply current performance, enabling designers to integrate with their designs. The 50 Ohm internally matched amplifiers minimize the use of external components, thus simplifying system integration. Active bias circuitry is incorporated to minimize performance variations due to temperature.
“In response to the industry needs for cost-effective and high-performance RF solutions, we are proud to announce this new series of high-performance general-purpose amplifiers designed for a wide range of wireless applications,” said Morteza Saidi, Vice President of Engineering at WJ Communications. “By leveraging WJ’s RF design expertise and the advanced InGaP HBT (GaAs) process technology, WJ is now offering 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.”
Product Overview
The WJA10xx & WJA15xx amplifiers are broadband products, housed in a small, RoHS-compliant, and SOT-89 surface-mount package. The new amplifier family includes both RF and IF devices, offering high linearity and low current. The WJA series can be operated from +5V supply, and have P1dB of 20 dBm, 15 and 20 dB of power gain and OIP3 of 35-43 dBm. With built-in active biasing circuitry, designers can reduce the performance variations over the temperature.
Value proposition
Responding to market needs for small-signal amplifiers with high linearity and low current, WJ has developed a series of active bias amplifiers, WJA series. The following are key features of the WJA amplifier family:
- Broadband and High Dynamic Range
– Diverse applications from 50 to 4000 MHz frequency
