ANADIGICS Announces 10 Gb/s Wideband Limiting Amplifier; Enabling Solution for High Speed OC-192/STM-64 Network Design.

SAN JOSE, Calif.--(BUSINESS WIRE)--February 24, 1998--ANADIGICS, Inc., the leading supplier of GaAs products for fiber optic communications applications, today unveiled its new monolithic limiting amplifier for use in high speed SONET OC-192 and SDH STM-64 Receiver applications. Offering high speed DC-10 Gb/s operation, and including low pulse width distortion, small signal gain and differential input/output among its innovative performance features, the ALA90000 is a market-leading technology solution which meets the needs of high speed, high capacity network design today.

The ALA90000 is a 3 stage, DC coupled, differential amplifier IC, which replaces a multistage discrete amplifier solution typically needed after transimpedance amplifiers or PIN-amps in OC-192/STM-64 Receiver applications. The new amplifier has a small signal gain of 25 dB, input sensitivity of 7mV (differential) and an output drive (Vout, p-p) of 700 mV into 50 ohms.

"The ALA90000 offers 10 Gb/s differential in/out operation, 25 dB small signal gain, and built-in DC input offset cancellation which automatically biases the input stage in the optimal high gain region," said Tony Jayakumar, Program Design Manager. The ALA90000, which operates from a single 5V power supply, offers 3 dB bandwidth of 7 GHz and rise and fall times of 50 psec. "This monolithic solution allows our customers to build smaller receivers with the performance advantages of our PHEMT devices. It can also be used as an universal gain block in OC-192 systems."

"As thirst for bandwidth increases, designers need high-performance chip-sets to build faster fiber optic networks," said Dan Trepanier, Sales Manager, Fiber Optics. "The ALA90000 offers high speed with DC-10 Gb/s operation, 25 dB small signal gain, and built-in DC Input Offset Cancellation. It's a great solution with the features to meet network design needs today!"

The ALA90000 is manufactured using ANADIGICS' Pseudomorphic High Electron Mobility Transistor (PHEMT) process, which achieves extremely high electron mobility. This new device class has better gain and bandwidth than conventional MESFET devices and hence is an enabling technology that serves the high data rate (10 Gb/s or better) systems.

The ALA90000 is sold in die form. It is available at $300 in quantities of 1,000. The amplifiers are manufactured at the company's state-of-the-art facility in New Jersey, and are 100% tested at DC and RF before shipping.
