40-876-002 -
Pickering Interfaces Ltd.
The 40-876-002 is a 50 Ohm 4 to 1 RF multiplexer with 2 banks in a single PXI slot. Additionally, extra switching allows the common connection to be terminated into 50 Ohm, maintaining signal integrity. The module has low insertion loss and VSWR through the use of modern RF relay technology at an affordable cost. Each MUX has been carefully designed to ensure excellent and repeatable RF characteristics to frequencies of 3GHz with each path having a nominally equal insertion loss. The injection of noise and unwanted signals into the signal paths of the 40-876 has been minimized by careful attention to the mechanical and electrical design.

Coaxial attenuators are constructed with passivated stainless steel for durable use in both engineering labs and production line environments. These coaxial attenuators are designed and manufactured for low VSWR, low insertion loss and high attenuation value accuracy. The standard offering covers the frequency range of DC to 110 GHz and includes various interface options from 2.4 mm to 1 mm connector types as well as both male and female interfaces. The power handling of standard models is 0.5 to 1 watt continuous wave (CW). Higher power handling levels and different attenuation values and connector types from those listed below can also be requested.

HIGH-POWER RADIO FREQUENCY (RF) AND MICROWAVE AMPLIFIERS, TWTA AND SOLID STATE -
Communications & Power Industries
electromagnetic compatibility (EMC) high-intensity radiated field (HIRF) testing, military testing, electronic warfare simulation and scientific applications are based on the same switched-mode power supply technology as its rugged amplifiers. As a result, these instrumentation amplifiers have all the same performance and reliability advantages as the rugged product line, but have been neatly re-packaged into compact, lightweight and affordable rack-mountable units more suitable for less demanding physical environments. CPI TMD's new modular design (the PTCM range) has many user benefits, including advanced self-diagnostics, ethernet interfaces, remote management, VSWR protection and plug and play field replaceable power supplies.

Dow-Key Mircowave Corporation
An electromechanical switch made primarily for routing microwave signals/RF energy from one point to another within a transmission line. Coaxial switches can be used in either an industrial environment or in the lab. These electromechanical devices are also used for RF testing equipment and in large RF communication systems and networks. Coaxial switches vary by port configuration, switch type, maximum frequency, isolation, insertion loss, voltage standing wave ratio (VSWR) and package type. Coaxial switches are able to route RF signals over a broad bandwidth from DC to 40 GHz, and are now offered with the Low PIM option which will improve Passive Intermodulation levels from -110dBc (standard switch) to -160dBc.

Fairview Microwave Inc.
Fairview Microwave’s semi-rigid test probe assemblies come in multiple cable diameters to help when attaching the unterminated end of the probe to a circuit board trace. There are two versions including straight-cut probe ends for those that would like to customize the dimensions of the center conductor and dielectric dimensions, as well as pre-stripped probe ends that are ready for immediate use. By soldering the outer conductor to the signal ground and the exposed center conductor to the trace carrying the signal of interest, simple sampling measurements can be made without having to create a separate subassembly circuit board or add a connector to the circuit layout which can take up valuable real estate. Fairview provides 3 diameters of semi-rigid coax and 3 different lengths from 3 inches to 12 inches to fit a variety of trace widths and applications. All test probes are 100% RF tested to ensure the cable assemblies operate to 6 GHz and also to make sure that the SMA connector interface meets the 1.35:1 VSWR specification prior to shipping. To protect the small diameter coax from damage, each part is shipped in a clear protective tube that can also be used for storing the probes for future use.

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.

PXI RF Relay Modules offer single-pole double-throw (SPDT) and terminated switches. SPDT models include excellent insertion loss, voltage standing-wave ratio (VSWR), and isolation parameters to minimize signal degradation. You can use the onboard relay-count-tracking feature on these models to predict relay lifetime and reduce unexpected system downtime. SPDT models are also well-suited for passing high-order harmonics from PXI RF Signal Upconverter Modules or routing multiple sources to PXI RF Signal Downconverter Modules. Terminated switch models feature front-mounted SMA connectors and high-performance solid-state relays for fast switching time and unlimited mechanical lifetime. These models also include termination on every COM line and channel, which helps minimize reflections of the RF signal and protect your instruments.
