Isolated Four-Port Serial Interface Cards
PCI-ICM422-4 and PCI-ICM485-4
These cards can be installed in any 5-volt PCI-bus computer that can accommodate "long" cards and are designed to provide effective communication on long communication lines in noisy environments. The data lines are opto-isolated from the computer and from each other to assure communication even when large common mode noise and voltages are superimposed. Type 16550 UARTs are used. These include a 16-byte transmit/receive FIFO buffer to insure against lost data in multitasking operating systems. All ports are independently addressable and an on-board crystal-controlled oscillator permits precise selection of baud rates up to 115,200 baud or, by changing a jumper, up to 460,800 baud.

Power Supply
The Power Supply Systems are the heart of any experiment. They provide the High voltage and Low voltage required by the detectors and by the related front-end electronics. The quality of the power supply is critical to obtain the best performance from the set-up. The sensibility of modern detectors, in fact, make them susceptible to any even small variation in the power supply, and so features like low Noise, low Ripple and high stability become essential in the design of a performing power supply system. Strong of 40 years of collaboration with the most important research labs worldwide CAEN offers today sophisticated High Voltage Power Supply and Low Voltage Power Supply Systems. The demonstration of this successful long-standing tradition is the “CMS Crystal Award 2009” that CAEN received for the development and production of the power system for the CMS tracker. CAEN offers a wide selection of Power Supplies in different form factors and standards:- For smaller set-ups Standalone or modular (NIM / VME) products or are the ideal fit.- For bigger set-ups, where a high number of High voltages and Low voltages is required, the Mainframe Systems and Boards (up to 48 channels/board, up to 768 channels in a single Mainframe) are the most recommended.

RF Front-End ICs
Analog Devices offers RF Front-End ICs for phased array antenna solutions. These RF Front-End ICsare placed right at the antenna element and can quickly switch between transmit and receive functions in radar applications. The power amplifier on the transmit side is highly efficient operating in short pulse durations. The low noise amplifier on the receive side has a low noise figure with high linearity so that it won’t distort the incoming return signal. The RF Front-End IC also incorporates a high performance switch to toggle between the transmit and receive paths. Highly integrated planar phased array antennae need small form factor solutions, and Analog Devices has integrated the switch, low noise amplifier, and power amplifier into a small surface mount package as well as the decoupling capacitors, providing an optimal solution.
