Amplitude Detectors with Isolators
Full band waveguide detectors are GaAs beam lead Schottky diode-based detectors that are specially designed for millimeterwave network analyzer applications. With a proprietary circuitry design and careful diode selection, these zero-biased detectors exhibit high sensitivity and extremely flat output characteristics. The below standard offering covers the frequency range of 18 to 170 GHz and offers a 1 MHz video bandwidth and 1 MΩ video output impedance. The standard models also have the capacity to handle a maximum RF input power of up to +17 dBm. The RF interface of these detectors is a standard waveguide with an integrated Faraday isolator to improve the port VSWR. The output voltage polarity is negative and the connector type is a female SMA. Other configurations are offered as custom models.

Digital RF Power &V.S.W.R. Indicator
PowerMaster Series
Thank you very much for purchasing the Array Solutions PowerMaster Series RF Power/VSWR Indicator. The PowerMaster represents a breakthrough in features for measurement of the performance of your transmitting system. Microprocessor control insures fast capture time and low power consumption. With the ability to monitor your VSWR and power levels at all times, you will know that your transmitter, RF source, and load, or antenna systems are operating effectively and safely. In addition, the power and VSWR relay alarms can quickly shut down your power amplifier system and alert you to the alarm condition. This places an additional layer of protection in your transmitting system to help preserve expensive tubes and finals. The PowerMaster also features the ability to be monitored and controlled from a PC via the bundled software, and the unique ability to be monitored and controlled over a LAN or from the internet. PowerMaster firmware updates will be made available for download from the Array Solutions website as they becomeavailable. This means that the user can take full advantage of features or enhancements just by installing the firmware update. No need to return the meter to the factory for updates.

Broadband Detectors
These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode. The high sensitivity zero bias GaAs diodes can also be special ordered for use at lower frequencies when highest sensitivity is required.

As standard practice, all of our SMT assemblies are washed and tested through our Automated Optical Inspection and pass through our stringent internal QA/QC policies. In Cables and Wire Harnesses, pretests, such as pull tests and crimp type tests, are performed on all builds before being tested for continuity, hi-pot, shorts and mis-wires, to name a few. Our electromechanical assemblies are capable of receiving full functional testing through custom test fixtures and RF test. Some RF tests include Gain/Loss, Frequency Response, VSWR (Voltage Standing Wave Ratio), Inter-Modulation Distortion and Output Power.

High Flexibility VNA Cables
Our lines of high frequency VNA test cables display excellent electrical properties such as wonderful phase stability of +/- 6° at 50 GHz and +/- 8° at 67 GHz as well as VSWR of 1.3:1 at 50 GHz and 1.4:1 at 67 GHz. The 50 GHz assemblies are terminated with 2.4mm connectors while the 67 GHz versions utilize 1.85mm connectors. The braided stainless steel armoring surrounding the coax provides a rugged, but flexible cable with a flex life exceeding 100,000 cycles, making these test cables ideal for use in semiconductor probe testing, precise bench top testing as well as lab/production testing where the need for a highly flexible, yet durable cable solution is required. The VNA test cables are also equipped with rugged stainless steel connectors that provide up to 5,000 mating cycles when attached with proper care. Additionally, the flexibility of these cables makes it easier and safer to test a Device Under Test (DUT). A swept right angle 2.4mm and 1.855mm connector option allows these cables to fit in tight spaces and can reduce the length of cable required in many applications.
