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 […]

Relay Controlled Programmable Attenuators

These new relay controlled programmable attenuators offer accurate and stable performance with very low harmonic distortion (IMD) and cover multiple RF frequency bands down to DC. They are popular for use in military and commercial satellite and ground communication systems, cable modem and cellular telephone testing, radar, telecommunications, and automatic test equipment (ATE). Six models […]

Power Amplifier Accessories A new series of RF and microwave power amplifier accessories includes heat sinks, heat sinks with cooling fans, and power control cable assemblies. There are eight different heat sink models, some of which are designated for general purpose usage, with others configured for select power amplifier models. PASTERNACK (9)

PIN Diode Waveguide Switches

A new line of E- and W-Band PIN diode waveguide switches, SPST and DPDT millimeter wave waveguide switches, are reflective designs that operate over an ultra-broadband frequency range with fast switching performance. They consist of four models with fully integrated WR10 and WR12 waveguide ports covering popular E-Band (60 to 90 GHz) and W-Band (75 […]
