Anadigics adds three new Small-Cell Power Amplifiers
Anadigics has introduced three new power amplifiers (PAs) optimised for 3G and 4G small-cell applications, including picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE). The amplifiers are built using the company's InGaP-Plus technology.
The AWB7133, AWB7137, and AWB7238 operate in the 2496 MHz to 2690 MHz, 758 MHz to 803 MHz, and 791 MHz to 821 MHz frequency band, respectively, delivering a combination of efficiency, linearity, output power, and thermal characteristics ideally suited to small-cell applications.
"Anadigics continues to expand its industry-leading small-cell power amplifier family to address the most popular WCDMA, LTE FDD and TD-LTE frequency bands," said Charles Armour, senior director of business development for Wireless Infrastructure Products at Anadigics. "As wireless data consumption continues to break records, our power amplifiers enable the design of high throughput, reliable, and compact small-cell base stations. These solutions enable service providers to economically and pragmatically expand broadband network capacity and coverage."
The AWB7133 and AWB7137 power amplifier devices deliver better than 15 percent efficiency, 28 dB gain, and -47 dBc ACPR @ +24.5 dBm of linear output power. The AWB7238 power amplifier features 13.5 percent efficiency, 30 dB gain, and -47 dBc ACPR @ +27 dBm linear output power.
These power amplifiers are available in the compact, low-profile 7 mm x 7 mm x 1.3 mm surface mount package used across theAWB71XX and AWB72XX product lines, allowing the same PCB layout to be used for different bands and power levels. Anadigics' small-cell power amplifiers offer integrated bias, which eliminates the need for complicated external circuitry and reduces PCB space requirements.
