High-Reliability Frequency Dividers Cover Wide Frequency Bands

Pasternack recently launched a new line of frequency-divider modules that cover broadband frequencies ranging from 0.1 to 20 GHz.

A selection of 28 different models is offered with a variety of fixed divide-by-ratios from 2 to 40. These prescalers are well-suited for use in phase-locked-loop (PLL) and frequency-synthesizer circuit designs, as well as test instrumentation. Typical applications include use in aerospace and defense, satellite communications, VSAT, test-and-measurement equipment, and point-to-point radio networks.

Designs are available in compact and rugged SMA connectorized packages. Circuit assemblies feature advanced gallium-arsenide (GaAs) HBT MMIC semiconductor technology that produces low additive single-sideband (SSB) phase-noise performance with typical levels down to -155 dBc/Hz at 100 kHz offset. Input power ranges from -20 to +15 dBm, while output power ranges from -6 to +5 dBm, depending on the model.

All Pasternack frequency-divider modules are designed for high reliability, claims Pasternack. Most models are guaranteed to meet MIL-STD-202 environmental test conditions for humidity, shock, vibration, and altitude. Some models are hermetically sealed and guaranteed to meet MIL-STD-883 environmental test conditions for temperature cycles, and fine and gross leak.

"Our new line of frequency-divider modules covers wide frequency bands from 0.1 to 20 GHz and offers a broad selection of fixed divide-by-ratio configurations. Designers will find this comprehensive selection desirable to optimize performance for PLLs and other applications," said Tim Galla, product manager, Pasternack.

The new frequency dividers are in stock and available for same-day shipping with no minimum order requirement. For detailed information on the products, visit here.
