Sol Chip Pak Replaces Batteries ...

We've just learned of a significant USA design win for the patented Sol Chip Pak™ (SCP-R2801) Power Modules to control LED lighting fixtures.

They offer 24/7 non-stop functionality by combining state-of-the-art solar cells, a rechargeable battery, and advanced power management circuitry. These power modules include all the components that are required to harvest energy from ambient light, charge a built-in rechargeable battery, and deliver a stable voltage to a load. Sol Chip’s patented technology integrates solar energy conversion with very large scale integration (VLSI) techniques to produce unique ambient light harvesting devices that can even extract energy from office lighting to provide constant power. These versatile boards, based on Sol Chip’s unique Saturn cells, provide power even in office light conditions.

The output voltage of these "everlasting solar batteries” is regulated to 3.6V, but other voltages are available by request to suit alternate applications. Versions are available with 1, 2, 3, or 6 Saturn solar cells depending on the power needs. The 6-cell version provides an average output current of up to 750mA from the integrated solar cells, with up to 1.5A peak current. The capacity of the 3.6V onboard rechargeable batteries in the series is 190 - 1100mAh. 

The SCP series of boards allow product designers to build fit-and-forget light-powered products that can recharge themselves. Existing products can be modified by simply disconnecting a device’s traditional batteries and plugging in an SCP to create a self-powered, no maintenance device. All that is needed is a small window to allow light to reach the board - it does not even need to be pointed to the sky. Operable in sunlight and indoor environments, it removes the need for a battery power source in low power applications, removing maintenance headaches and hazardous battery waste issues. 

Incorporating an SCP module into mobile designs is perfect for hard-to-reach locations, and eradicates the significant costs and time associated with installing and maintaining wiring to connect deployed sensors, and thus reduces the cost of system ownership. The SCP series is ideal for designing in to remote sensors and monitoring systems that are used in diverse applications such as: agriculture, farming, drip-irrigation systems, weather testing, as well as security, IoT, wireless sensor networks, wearable electronics, etc. Other applications include smart city solutions for everything from parking to security and utility meters, data loggers, GPS emergency locators, animal tracking devices, GPS asset/container tracking, GPS vehicle tracking, environmental measurement and radio frequency identification (RFID) devices, etc.
The design win incorporates the solar chips on to the customer's own PCB, thus saving significant costs.

Pocketable RF spectrum analyzer provides features comparable to full-size desktop analyzers in a tiny package.

The Triarchy Technologies VSA6G2A Vector Spectrum Analyzer is an economical USB RF tool that plugs into the USB port of a PC and is controlled with the provided PC application software.  It offers almost all of the functionality of a benchtop spectrum analyzer.  Its frequency range of operation is from 100Hz to 6.2GHz, with an amplitude measurement range of -140dBm to 24dBm. The RBW (resolution bandwidth) range is from 0.2Hz to 10MHz and the noise level (DANL) is as low as -140dBm.  

The VSA6G2A is very compact (4” x 1” x 1”) and easy to use. The software user interface has been designed to resemble the front panel of a standard desktop spectrum analyzer, allowing users to use the application intuitively without a steep learning curve. Touch screen support is also provided, making the VSA6G2A quick to operate.
The VSA6G2A’s demodulation capabilities allow it to measure analog and digitally modulated signals, such as AM, FM, PM, MSK, and QPSK. Additionally, the VSA6G2A has I and Q signal ports, enabling it to work as a wide-band I/Q receiver platform. Visualizing pulse modulated signals is usually not very easy, but with the VSA6G2A’s trigger input it is straightforward to view these waveforms. 
The analyzer’s operation is divided into two bands to cover the complete operating range: a low band (100Hz to 2MHz) and a high band (1MHz to 6.2GHz). The VSA6G2A offers an N (female) RF signal input connector and a mini-B USB connector for interfacing with the PC. Four MMCX connectors provide I/Q port access.
Signal spectra are clearly displayed on the attached PC, as well as density, waterfall images, and demodulated waveforms and eye diagrams.  The waterfall display helps in showing signals like frequency hopping Bluetooth. The VSA channel power function makes it simple to measure signal power automatically.  Production testing is also facilitated when using preselected Pass/Fail criteria. 
Weighing only 3.5oz and powered from a PC’s USB port, the VSA6G2A is ideal for field test and installation since it can be easily slipped into a laptop bag and used for monitoring RF signals in temperatures from -10decC to +50degC.  It is also suitable for use in benchtop EMC testing with near-field antennas.
