Ted Rappaport, founding director of NYU WIRELESS and a leading proponent of using the millimeter wave spectrum for wireless communications, discusses the FCC's recent rulemaking actions and technology developments that are paving the way to 5G.
The LTC6430-20, a 20 MHz to 2 GHz differential input and output 20 dB gain amplifier from Linear Technology Corp., offers outstanding linearity of +51dBm OIP3 (Output Third Order Intercept) and 2.9 dB noise figure at 240 MHz.
With the new PicoScope® 9341 20 GHz Sampling Oscilloscope, engineers can analyze two differential or four single-ended high-speed signals. The instrument is ideal for measuring skew and crosstalk between differential pairs on serial buses such as HDMI, SATA and PCIe, and for testing signal integrity at differential and single-ended transceiver ports. Data rates up to 40 Gb/s can be viewed, with 5th-harmonic characterization possible up to 8 Gb/s.
Vectron International announces the VC-826 differential XO in a 3225 (3.2 x 2.5 mm) package. The VC-826 XO is designed to support applications that require low jitter (under 200 fsec) at standard frequencies from 20 to 170 MHz. Vectron's VC–826 is designed for use with PHY/SERDES, high speed converters, ASICs and FPGAs in communications platforms, medical and industrial markets.
Linear Technology Corp. introduces the LTC2323-16, a dual 16-bit 5 Msps simultaneous sampling, successive approximation register (SAR) ADC with flexible differential inputs. The LTC2323-16 supports a wide input common mode range and simplifies system-level design by relaxing the signal conditioning requirements to drive the ADC with a wide range of analog signals up to Nyquist frequencies.
The Molex SpeedStack™ mezzanine connector system provides a low profile solution for PCB space savings and a narrow body width for optimized airflow in high-speed and very dense applications. Compact SpeedStack connectors feature a stack height of 4.00mm and support data rates up to 40 Gbps per differential pair. SpeedStack connectors will be displayed at Molex booth 117, DesignCon 2014.
Linear Technology Corp. introduces the LTC2338-18, an 18-bit 1 Msps no latency analog-to-digital converter (ADC) with a wide ±10.24 V fully differential, true bipolar input range for high voltage, industrial applications. The device operates from a single 5V supply, achieves 100 dB SNR and -110 dB THD and features an internal 2.048 V (20 ppm/°C max) reference and reference buffer. An input divider network scales and level shifts the input signal, eliminating complicated circuitry required to directly interface true bipolar signals.
SenarioTek, a leading designer and manufacturer of RF and microwave products, announced the differential product extension of the FlexMatrix reconfigurable RF switch matrix series targeting the automation and characterization of high-speed devices.
Isola Group S.a.r.l., a market leader in copper-clad laminates and dielectric prepreg materials used to fabricate advanced multi-layer Printed Circuit Boards (PCBs), announced its new low loss, low skew, high-speed material, GigaSync™. This product has been engineered to eliminate skew issues in high-speed designs that use differential pairs to create a balanced transmission system able to carry differential (equal and opposite) signals across a printed circuit board.
In addition to various new options for its oscilloscopes, Rohde & Schwarz has continued to expand its range of probes as well: Available for the first time on the market, there is now a broadband, ground-referenced model with a range up to 6 GHz. A differential high-voltage probe is also available.
Analog Devices Inc. (ADI), a world leader in high-performance semiconductors for signal processing applications and RF ICs, introduced a dual-channel differential amplifier for driving high speed 12- to 18-bit A/D converters. Featuring a 3dB bandwidth of 4.5 GHz, the ADL5566 differential amplifier is optimized for wideband, high IF (intermediate frequency), low distortion, and noise performance out to 500 MHz.
