RF Mixers & Frequency Converters Overview
-
Up and down conversion is often used because waveform generation in a transmitter is less expensive at lower frequencies and the dynamic range of analogue-to-digital converters in the receiver is higher at lower frequency.

Particle Counter
VLT-E9700
-
Modern diesel engines are quite clean, provided the soot filter is present and working properly. A soot filter can get clogged, or even malfunction. In that case the filter has to be cleaned or replaced. Unfortunately, sometimes the vehicle owner has the filter removed altogether. When the filter has been physically removed, it is ‘programmed out’ of the vehicle software, so that the removal of the filter remains undetected during an (E)OBD check. This is why in ever more countries a particle count is mandatory during a periodic inspection of e diesel vehicle.

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 Converter Unit
FCU
-
The Astronics Frequency Converter Unit (FCU) provides frequency conversion of variable frequency aircraft power. Recent trends in aircraft power systems use variable frequency (VF) generators instead of fixed frequency of 400Hz. While the majority of aircraft loads can use VF power, select loads still exclusively require 400Hz and are best addressed by the use of FCUs. The FCU performs the task of converting the power line frequency by leveraging recent advances in solid-state technology to provide dramatic improvements in performance over traditional frequency converter solutions.

2-18GHz Instantaneous Frequency Measurement Unit
DR073
-
Teledyne Defence & Space’s Instantaneous Frequency Measurement (IFM) module, also known as a Digital Frequency Discriminator (DFD), offers high speed frequency measurement across the full operating bandwidth.The IFM measures the frequency of RF signal present at its input and presents a result at its output as digital data. The RF input signal is conditioned by an RF amplifier that provides sufficient drive for the frequency resolving circuits. The raw video from the resolvers is digitised and processed into the required output format. There is additional timing and control circuitry which initiates the measurement process and provides handshake data to the host system processor.

VDI Millimeter-Wave Frequency Extension Modules for PXA, MXA, EXA Signal Analyzers
-
These modules offer low conversion loss and excellent noise figure. Standard features include dual operating modes. First, the module can function as a high performance down-converting mixer. The second operating mode functions as a block down-converter with a broadband IF up to 20 GHz. Power to the module is provided via an included external DC power supply. These frequency extenders minimize conversion loss by multiplying and amplifying the LO signal internally, thus taking advantage of the benefits of low harmonic mixing. This architecture also preserves the X-Series precision frequency resolution and low phase noise, extending those qualities into the millimeter and sub-millimeter bands.
