• LMX2595: Single Frequency Problem

  

  Ian Carmack

  Part Number: LMX2595 Tool/software: All I am having trouble with an LMZ2595 synthesizer. It will produce almost every frequency I want (simple single frequencies, no modulation or chirps). But on some PCBs the part will not produce 2.5 GHz. There is…

• RE: LMX2595: How to make 15dB of attenuation with lmx2594

  

  dharani vykuntam

  Hello Noel Fung, From your suggestion, I made OUT_ISET = 3 in R45 register, I observed the variation in current drawing and output power also. but, this is not sufficient for us. kindly suggest us the possibility to attain 15dBm of attenuation. we need…
