Eight-bit A/D Converters
ADI released two eight-bit, high speed, low power, low noise analog-to-digital (A/D) converters designed for instrumentation and communications applications. Both eight-bit high speed A/D converters use a pipeline architecture and consume 310 mW of power. The AD9284 is a dual, eight-bit, 250-MSPS A/D converter while the AD9286 eight-bit 500-MSPS A/D converter delivers eight-bit resolution at 40 percent less power than competitive components. The converters feature high SNR of 49.3 dB FS and allow for a wide dynamic signal range with SFDR performance of 65 dBc. Applications for these components include battery-powered instruments, handheld scope meters and digital oscilloscopes.

Components

Surface-mount Limiters
The LM Series of surface-mount limiters is designed for receiver protection applications through 8 GHz. These RoHS-compliant devices provide high power protection at levels to 100 W CW and 2 kW peak power in surface-mount-technology (SMT) packages measuring only 8 × 5 × 2.5 cubic mm. Ideal for receiver protection applications at L-band (1 to 2 GHz), S-band (2 to 4 GHz) and C-band (4 to 8 GHz) frequencies. LM Series limiters provide considerably higher thermal capacity than silicon and GaAs MMIC solutions. Their small size and excellent thermal conductivity supports low-profile circuit designs without sacrificing protection for sensitive receiver front-end components.

Semiconductor/IC

Ultra-low-noise Heterojunction FET
The NE3520S03 ultra-low-noise heterojunction field effect transistor is claimed to feature industry-leading low noise characteristics for 20 GHz satellite broadcast reception. To reduce noise at ultra-high frequencies, the NE3520S03 employs a new epitaxial wafer structure that leverages high electron density, thin-layer technology. This increases the velocity at which the electrons move through the channels and lowers the source resistance, making possible a noise figure of 0.65 dB, which is among the lowest in a mass produced product for the 20 GHz band, and an associated gain of 13.5 dB.
