Polaris’ Microwave Frequency Synthesizer (PMFS series) operates in the frequency range from 3.4 GHz to 35 GHz and is categorized into PMFS-F series, PMFS-V series, and PMFS-P series. The PMFS-F series is a fixed frequency synthesizer, the PMFS-V series is a variable frequency synthesizer, and the PMFS-P series is a high power fixed frequency synthesizer capable of outputting RF power up to 20dBm. The PMFS series employ a fractional-N PLL architecture to provide fine frequency resolution with excellent spurious and phase noise performance.
The PFPS-V series provides a simple UART interface for user to change the output frequency easily and is available in a variety of configurations, including a RF output power and output frequency range options. This series has a non-volatile memory feature that will return to the last set frequency when power is turned on. The PMFS-V series has internal or external reference and are designed for rugged, compact and to operate at low power consumption.
