New RF Frequency Dividers Offer Broadband Coverage

Advanced GaAs HBT MMICs cover 0.5 GHz to 18 GHz for high-rel applications

Pasternack, a provider of RF, microwave and millimeter wave products, has announced a new line of high-rel frequency dividers that cover wide frequency bandwidths from 0.5 to 18 GHz and are available in 2, 4, 5, 8, and 10 divide-by-prescaler configurations.

These modules are suitable for use in common phase locked loop and frequency synthesizer circuit designs that may involve applications for aerospace and defence, satellite communications, VSAT, test and measurement equipment, and point-to-point radios.

The new frequency dividers are said to use advanced GaAs HBT (heterojunction bipolar transistor) 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 +10 dBm with output power ranging from -1 to -4 dBm depending on the model. Additional performance includes a fast output transition time of 100 picoseconds, high reverse leakage levels up to 85 dB, single +5V DC power supply, and an operating temperature range of -55 to +85degC.

All models are EAR99. These frequency dividers are designed into compact miniature packages that support field replaceable SMA connectors and mounting fixtures that can be removed for PCB drop-in applications.
