New products in Pasternack´s assortment – flexible waveguides and VCOs

The Pasternack Enterprises company recently supplemented its range of new products with flexible waveguides and voltage controlled oscillators.

Pasternack expands their waveguide product portfolio with the addition of new flexible waveguides that operate up to 40 GHz over nine frequency bands. This offering consists of 36 unique models of flexible waveguide twists ranging in size from WR-137 (as low as 5.85 GHz) to WR-28 (up to 40 GHz). Pasternack’s flexible/twistable waveguides, also referred to as a “flexguide”, utilize helically wound silver coated brass strips surrounded by a flexible and twistable, yet durable, neoprene sleeve. The ends of the waveguide are terminated with brass flanges available in nine waveguide sizes and multiple flange styles. Typical VSWR for these flexible waveguides ranges from 1.05:1 up to 1.35:1 depending on waveguide size and frequency. Insertion loss performance is similar with typical levels as low as 0.07 dB. These waveguides will flex in both the E and H planes and can also twist. Flanges in lower frequency versions are available in both UG and CPR styles. The new flexible waveguides sections from Pasternack act as a malleable conduit in waveguide systems where there is not perfect alignment for a traditional rigid waveguide section. Often an ideal solution for test labs or prototyping, these flexible waveguides can easily be flexed and twisted to conform to various misalignments in waveguide systems.

Another new products in assortment is a new line of voltage controlled oscillators covering select bands from 10 MHz to 11 GHz in a variety of package options. This line of voltage controlled oscillators is most commonly deployed in applications such as phase locked loops, frequency synthesizers, electronic jamming equipment and function generators. Pasternack’s new voltage controlled oscillators, commonly referred to as VCOs, are a type of oscillator where the frequency of the output signal can be varied by adjusting the amplitude of the input tuning voltage. The performance characteristics play a critical role in overall system performance. Unlike oscillators with a single fixed frequency, VCOs have a range of frequencies making them desirable with designers.

A comprehensive and growing portfolio of VCOs from Pasternack includes over 60 different models in true surface mount and coaxial packaged versions available from stock. Some models have added features which include integrated buffer amplifiers and input modulation ports. Tuning voltages can range from 0 to 20 volts, output power ranges from 0 to +12.5 dBm, and all models have an operational temperature range covering -40°C to +85°C. These VCOs also boast exceptional phase noise performance as low as -125 dBc/Hz at 10 KHz offset. All designs are highly reliable and are designed to meet a series of MIL-STD-202 environmental test conditions, which include shock, vibration, and temperature cycle.
