Frequency divider modules with field replaceable SMA connectors

Pasternack has introduced a new line of high-rel frequency dividers that cover wide frequency bandwidths from 0.5 to 18GHz and are available in 2, 4, 5, 8, and 10 divide-by-prescaler configurations. The modules are ideal 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 frequency dividers employ advanced GaAs HBT MMIC semiconductor technology that produces low additive single sideband (SSB) phase noise performance with typical levels down to -155dBc/Hz at 100kHz offset. Input power ranges from -20 to +10dBm with output power ranging from -1 to -4dBm depending on the model. Additional performance includes a fast output transition time of 100 picoseconds, high reverse leakage levels up to 85dB, single +5VDC power supply, and an operating temperature range of -55C to +85C. 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 convenient PCB 'drop-in' applications. The rugged Kovar package designs are gold-over-nickel plated and hermetically sealed and 'guaranteed' to meet MIL-STD-883 environmental test conditions for temperature cycle and fine and gross leak testing, says the company. “Pasternack’s new lines of frequency divider modules with field replaceable SMA connectors are available in hermetically sealed packages that cover wide bandwidths from 0.5 to 18 GHz and support a broad selection of divide-by-prescaler configurations that are ideal for phase locked loop applications,” explains Tim Galla, Active Components Product Manager at Pasternack. “These versatile high-rel designs are available in-stock for immediate shipment.”
