9/17/2003 - Agilent Technologies Inc. (NYSE: A) introduced two low-cost, easy to use GaAs MMIC gain block amplifiers that provide high linearity, low noise and other key features to simplify system design. These amplifiers operate from 0.1 to 6 GHz and use state-of-the-art E-pHEMT (enhancement-mode pseudomorphic high-electron-mobility transistor) technology in the compact SOT-363 surface-mount package.
Today's wireless market places a high priority on time to market for new products. The Agilent MGA-6x563 series amplifiers accelerate time to market by offering a "smart bias" and 50-ohm match capability that simplifies system design. Designers can replace many different fixed-bias amplifiers by using the MGA-6x563's single external resistor to adjust the device's performance. This minimizes the number of external components required for matching and bias circuitry, thereby reducing the number of parts manufacturers need to specify and purchase.
The Agilent MGA-61563 and MGA-62563 amplifiers are primarily directed toward wireless applications such as cellular/PCS/WCDMA (wideband code-division multiple access) base station radio cards, WLL (wireless local loop), WLAN (wireless local area network), fixed wireless access and other high-performance applications. The Agilent MGA-61563 is recommended as a low-noise amplifier (LNA) or driver amplifier operating at up to 6 GHz. The Agilent MGA-62563 is recommended as an IF (intermediate frequency) amplifier operating at up to 3 GHz.
At 2 GHz, the Agilent MGA-61563 features +28.5 dBm third-order output intercept point (OIP3), +16 dBm linear output power (P1dB), 16.6 dB gain and 1.2 dB noise figure (NF). At 500 MHz, the Agilent MGA-62563 features +32.9 dBm OIP3, +18 dBm P1dB, 22 dB gain and 0.9 dB NF. The "smart bias" feature of these gain block amplifiers allows the drain current to be reduced, thus reducing the system's DC power drain, by adjusting the value of a single external resistor. In applications where the highest possible linearity (OIP3) is not necessary, reducing power consumption allows the device to run cooler, which increases its reliability.
U.S. Pricing and Availability
Agilent MGA-6x563 series E-pHEMT gain block amplifiers range from $0.99 to $1.06 each in 10,000 to 24,999-piece quantities. Both versions are available through Agilent's direct sales channel and through Agilent's worldwide distribution partners.
