Phase-locked loop (PLL) frequency synthesizer
150 MHz - 4.4 GHz ORMELABS

SYM4400 module is a very wideband / low noise RF synthesizer, providing many unprecedented features in its volume and price range. Offering as standard serial, I2C or SPI interfaces, it allows very easy integration. It accepts single voltage power supply with a very wide 6 to 30 V voltage range. On / off pulse modulation is also available as standard, allowing fast signals through very short rise and fall times (typ. 25ns).
Powered by a powerful ARM7 32 bits micro-controller, it reacts fast to control commands and can also work without an host thanks to an internal EEPROM memory and the possibility to store a number of discrete frequencies that can be programmed with a precise timing.
Output level can be set in the -15 to +15 dBm with 0,5 dB steps.
SYM4400 synthesizer module will ideally come as a replacement for laboratory synthesizers to integrate in production test benches, in multi-carriers test equipments, or as local oscillator sources.
