LMX2595: LMX2595

singam vamshi krishna
Intellectual 775 points
Part Number: LMX2595


respected sir

 1) I am generating two frequencies 17 GHz at the transmitting end and at the receiving end to down covert 17.070 GHz using two LMX2595 IC's. How do I achieve phase synchronization between these two synthesizer's such that at the receiving end to get a fixed Intermediate Frequency of 70 MHz. 

2) What type of pcb substrate material have you chosen to fabricate the entire schematic of the LMX2595 frequency synthesizer and what is the physical dimension (length, height, width) of the overall pcb as we are planning to make housing for the entire setup.

Thanks in advance

    Hi Singam,

    In your use case, is phase synchronization really needed? You can get the IF even if the RF and LO are not synchronized. 

    Anyway, please check ti.com for a video demo on how to do phase synchronization. 

    You can find the substrate information in the EVM user's guide.

    Dimension of the board is (not including the sma connector) 2480mil x 2170mil. Height is around 15mm.
