Today Arralis, the world leading W band device manufacturer, has added a number of new MMIC devices to its extensive product range. The new power amplifier, image cancellation mixer and variable attenuator come in response to new advance system requirements.
Arralis designs and manufactures high frequency semiconductor chips, modules and antennas up to and beyond 110GHz.
TU-W1330305 is a 4-stage MMIC power amplifier that covers frequencies from 92GHz to 96GHz. The TU-W1330305 provides up to 20dB of flat, stable gain, and a power output of more than 18dBm from a 4V supply voltage and remarkably low current at just 210mA.
Image Cancellation MMIC Mixer, 92 – 96GHz
TU-W1340310 is an I/Q MMIC diode mixer with integrated quadrature coupler for single sideband upconverter operation. TU-W1340310 is fabricated using GaAs Shottky diode technology and is designed for output frequencies in the range from 92GHz to 96GHz using either fixed IF and varying LO (86GHz – 90GHz) or fixed LO and varying IF (2GHz – 6GHz) signals, The circuit employs a double rat race configuration to effectively cancel image signals without filtering and offers superior signal to noise performance.
GaAs PHEMT MMIC Attenuator/ SPST Switch, 90 – 100GHz
The TU-W1401601 is a GaAs PHEMT diode based SPST switch and variable attenuator with a single input and output. The attenuation value may be adjusted to any value within the specified attenuation range. The chip is manufactured on a 50um substrate with 100um gate length. All bond pads and the die underside are gold plated. The control voltage ranges from +1.5V to -1.5V, the latter giving maximum attenuation
A packaged version of each device is also available with WR10 waveguide input and output on request.
Speaking from the European Microwave Week in London Arralis CTO, Mike Gleaves said, “We are delighted to participate in Microwave Week and again promote commercial 94GHz technology that exceeds expectations. We recently launched the worlds first W band up and downconverters and these have been a huge success for Arralis. We expect the same success with these new devices”.
Visitors to Arralis stand number 34 at European Microwave Week will learn more about these devices and also a number of other products will be on display. These include smart beam steering antenna technology, new communications and radar modules and a unique GNSS antenna with a very low SWaP specification.
