Amplifier Targets Set-Top Boxes And Residential Gateways

A new high-performance balanced linear amplifier is designed for residential gateway, set-top box and other digital interactive cable devices. The ABA 3100, a monolithic microwave integrated circuit (MMIC), is said to possess industry-leading noise and linearity performance in a cost-effective GaAs package. The ICÕs single-supply design delivers 12 dB gain across a wide 50- to 860-MHz bandwidth, while its balanced design results in a second-order output intercept point of +60 dBm. A high-linearity and low-distortion part, the ABA 3100 demonstrates a noise figure less than 3.2 dB across the 50-860 MHz CATV band. The device can also serve as a low-noise amplifier in advanced digital set-top boxes, compensating for the loss in signal level within the box. Housed in a surface-mount, 16-lead SOIC package, the ABA 3100 also suits cellular telephone operations, driver amplifiers, CATV fiber optic receiver/distribution amplifiers and CATV drop amplifiers. Price: $5 each/10,000. More details are available from ANADIGICS, Warren, NJ. (908) 668-5000.
