Gunn Diode Waveguide Oscillators

by Pasternack Microwave oscillators are used in a myriad of applications from mobile phones and GPS navigation systems to radios and test equipment. The purpose of the oscillator is to generate a continuous harmonic output with a defined frequency; this can be accomplished a number of ways. A typical oscillator consists of an active device […]

High-Speed End Launch Connectors

A new line of high-speed end launch connectors is comprised of four models that provide VSWR as low as 1.10:1 and a maximum operating frequency of 40 to 110 GHz. These millimeter-wave removable end launch connectors have options that include 1.0mm end launch (110 GHz), 1.85mm end launch (67 GHz), 2.92mm end launch (40 GHz), […]

Electromechanical Switches with D-SUB Connectors

A new line of electromechanical relay switches in popular configurations operates from DC up to 26.5 GHz and features a D-SUB multi-pin connector interface for secure and reliable DC voltage and command control functions. D-SUB multi-pin connectors provide a solderless, press fit reliable I/O connection that can be permanently locked down with a mating multiple […]

Fixed Attenuators

Twenty-three new quick connect fixed attenuators are available with QMA, QN, or 4.3-10 connectors for easy mating. These attenuators support operating frequency ranges from DC to 6 GHz. They boast attenuation values from 0 to 20 dB and VSWR as low as 1.15:1. PASTERNACK (90)

Methods of Suppressing PIM in Multicarrier Systems

by Steve Ellis, Product Manager, Pasternack Passive Intermodulation distortion (PIM) — the nonlinear effects that are observed from the passive components (i.e. antennas, cables, connectors, power dividers, and mixers)  of a system at high signal levels — is a phenomena of particular relevance in wireless infrastructures dedicated to the propagation of vast amounts of traffic. […]

New Oscillators Deliver Low Phase Noise

A new line of compact waveguide Gunn diode oscillators is tunable and generates signal levels that exhibit low phase noise at popular K- and Ka-band frequencies. They incorporate high performance devices and machined aluminum cavities. Due to the extremely high external Q and temperature compensation mechanism, these oscillators exhibit excellent frequency and power stability, lower […]

Phase Locked Oscillators

A new line of phase locked oscillators (PLOs) deliver accurate and stable output frequencies with low phase noise and spurious performance, making them ideal for use in radar and other exciter or frequency generation applications. Typical applications include phase locked loops, frequency synthesizers, function generators, and as a local oscillator source in receiver and transmitter […]

Cross Guide Couplers

A new line of cross guide waveguide couplers feature 4 port, 3 port and 2 port models with coax interface that work across C- to K-bands. The line consists of 160 parts in three sub-categories: cross guide couplers (4 waveguide ports), cross guide couplers with terminations (3 waveguide ports), and cross guide couplers with terminations […]

Electromechanical Switches

Twelve new models of electromechanical switches cover broadband frequencies from DC to 40 GHz. They exhibit very low insertion loss repeatability with guaranteed levels of 0.03 to 0.05 dB over 5 to 10 million switching cycles, depending on the model. The switches are offered in three configurations: SPDT, SP4T, and SP6T. They are designed with […]

Low-PIM Plenum-Rated Cable Assemblies

A new line of low-PIM, plenum-rated SPP-250-LLPL cable assemblies was designed for use in wireless infrastructure. The 36 new low-PIM jumper cables are made with UL910 plenum-rated SPP-250-LLPL cable and feature a maximum PIM level of -155 dBc. They deliver a maximum operating frequency of 6 GHz and a maximum VSWR of 1.25:1 up to […]
