General description :
The number and variety of video products on the market continue to expand. Even with the expansion of HDTV and high resolution RGB signals, the most common point-to-point connection for a video signal is analog. Intersil video ICs provide many solutions for moving these signals around. Whether it is transmitting RGB down CAT-5 or switching 32 security video feeds, Intersil has a solution. From high performance video amplifiers to differential line equalizers, Intersil's family of video products can address any portion of the analog signal chain.

General Description
The RMPA1766 Power Amplifier Module (PAM) is Fairchild's latest innovation in 50Ohm matched, surface mount modules targeting UMTS/WCDMA/HSDPA applications. Answering the call for ultra- low DC power consumption and extended battery life in portable electronics, the RMPA1766 uses novel proprietary circuitry to dramatically reduce amplifier current at low to medium RF output power levels (<+16dBm), where the handset most often operates. A simple two- state Vmode control is all that is needed to reduce operating current by more than 60% at 16dBm output power, and quiescent current (Iccq) by as much as 70% compared to traditional power- saving methods. No additional circuitry, such as DC- to- DC converters, are required to achieve this remarkable improvement in amplifier efficiency. Further, the 4 x 4 x 1.0 mm LCC package is pin- compatible and a drop- in replacement for last generation 4 x 4 mm PAMs widely used today, minimizing the design time to apply this performance- enhancing technology. The multi- stage GaAs Microwave Monolithic Integrated Circuit (MMIC) is manufactured using Fairchild HBT process.
Features
- 40% WCDMA efficiency at 28dBm Pout
- 20% WCDMA efficiency (58mA total current) at 16dBm Pout
- Low quiescent current (Iccq): 25mA in low-power mode
- Meets HSDPA performance requirements
- Single positive-supply operation with low power and shutdown modes
* 3.4V typical Vcc operation
* Low Vref (2.85V) compatible with advanced handset chipsets
- Compact Lead-free compliant LCC package - (4.0 x 4.0 x 1.0mm nominal)
- Industry standard pinout
- Internally matched to 50 Ohm and DC blocked RF input/output

PCB Automotive Sensors Debuts High Temperature Preamplifier
Operating to +120 °C for NVH Powertrain & Vehicle Underhood Testing
The Automotive Sensors division of PCB Piezotronics (PCB®) has announced release of a new high-temperature preamplifier, designed to overcome high temperature testing challenges associated with NVH powertrain and vehicle underhood testing applications, and to broaden options for NVH test engineers collecting acoustic data in high temperature areas.
Automotive engineers routinely perform NVH tests in areas around the powertrain, where elevated operating temperatures can present major measurement challenges. Underhood temperatures can peak at +125 0C under normal driving conditions, and can be significantly higher near turbochargers and exhaust system components, such as manifolds and diesel particulate filters. In the past, test engineers were limited by preamplifiers offering temperature ranges to + 70 °C. Model HT426E01 is a 1/2" preamplifier operating from ICP sensor power, terminating with BNC connector and utilizing standard coaxial cables. The model features a low attenuation factor (-0.06 dB) and low noise characteristics, 4.9 µV, based on an A-weight scale.
Common applications include underhood measurements for benchmarking and issue identification, including engine radiated, induction, ancillary and turbocharger noise; near-field measurements on manifolds; mufflers; exhaust after treatment components; and tailpipe noise. NVH groups within OEMs and Tier 1 suppliers involved with testing of powertrain components will benefit most from this product.
