Miniature 8-channel photon counter
id150 SERIES
-
Intended for large-volume OEM applications, the id150-1x8 is the only multichannel solid-state single photon detector on the market. It consists of a CMOS silicon chip packaged in a standard TO8-16pin header with a transparent window cap. The chip combines 8 in-line single photon avalanche diodes that can be accessed simultaneously for parallel processing. square in center-to-center A fast active quenching circuit is integrated within each pixel in order to operate each diode in photon counting regime. The chip is mounted on a printed circuit board on top of a single-stage thermoelectric cooler (TEC). A thermistor can be used to measure the temperature of the chip. Only two low power supplies of +5V and -25V are needed for operation in photon counting mode. The fast active quenching circuit leads to a dead time of less than 50ns per channel. An outstanding timing resolution of less than 60ps allows high accuracy measurements.

Frequency Synthesiser
RA062-F2
-
The RA062-F2 is a multiple LO module used to generate three pairs of LO signals, each pair being phase matched in order to provide the capability to drive two phase and amplitude matched, high sensitivity narrowband receivers such as might be required for an EW receiver system with DF functionality.The Stepped Frequency Synthesiser is based upon Direct Frequency Synthesis, DFS, whereby the 1GHz input reference signal is multiplied, filtered and mixed to generate a given number of isolated and filtered single tone CW signals from the 1GHz comb. A finely tuned signal is then generated using a multi-way switch to select between the 1GHz spaced CW tones and mixed with fine resolution signals generated using a custom DDS/VCO PLL network. In this way finely tuned signals can be generated between 7.5GHz and 23GHz.
