Frequency Dividers Cover 0.5 to 18 GHz Range

30 August 2016

RF and microwave components supplier Pasternack has announced a line of high-reliability 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 suited for use in common phase locked loop and frequency synthesizer circuit designs involving applications for aerospace and defense, satellite communications, VSAT, test and measurement equipment, and point-to-point radios.

The frequency dividers from Pasternack utilize advanced GaAs HBT MMIC semiconductor technology that produces low additive single sideband 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.

Other specifications include 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° C to +85° C. All models are EAR99.

The frequency dividers are designed into compact miniature packages that support field replaceable SMA connectors and mounting fixtures that can be removed for convenient PCB “drop-in” applications. The rugged Kovar package designs are gold-over-nickel plated, hermetically sealed and guaranteed to meet MIL-STD-883 environmental test conditions for temperature cycle and fine and gross leak testing.
