LNO-LP01M-RF - RF Synthesizer

RF Synthesizer 62.5MHz – 8GHz with output level up to +0dBm

Wideband frequency synthesizer (RF Signal Generator) with output frequency range from 62.5 MHz to 8 GHz with small frequency step. Output power is variable and AGC controlled with digital compensation system based on calibration data written in memory of the device. Synthesizer also has multi-path filtering block for additional harmonic suppression. Device is digitally controlled via SPI interface. Frequency tuning can be dynamically programmed within all specified frequency range. This device represents the modification of the LNO-HP02M-RF with slight difference in output stages. The main feature of this device is its low cost due to significant decrease of the output stage power.

Accessories

№ поз.	Компоненты	Кол-во	Описание
1	RS2SPI-01M-PCB	1	Evaluation board for RF-blocks with SPI-interface (like this) control via COM-port (RS-232) of the PC. This board serves as a RS-232 to SPI bridge
2	RF Debug Application	1	Software application for RF-blocks control via PC COM-port. Application has open source as it is written on Tcl/Tk and is used for easy learning of SPI control commands for particular RF-block, and for further integration of the block into user’s own complete system

Notes: accessories are not included in the product above, they should be ordered separately.

With aid of LNO synthesizer, RS2SPI board and RF Debug software one can easily assemble low-cost single or double RF-signal generator for test and measurement needs. You can learn more about it in the “How to assemble Low-cost RF-Signal Generator” article in the “Application Notes” section.

Output Frequency

Output frequency is given by the following equation

F_out=(M/N)·F_ref,

where F_ref — reference oscillator frequency (int. 150 MHz), N — integer in range from 0 to 2³² (provided that F_out is in range given by the table below), M — constant integer given by the following table for each appropriate frequncy range.

62.5-125MHz	125-250MHz	250-500MHz	0.5-1GHz	1-2GHz	2-4GHz	4-8GHz
